AEIS multiple-choice answers must be shaded on a personalised Optical Answer Sheet (OAS) using a 2B pencil, while answers written in booklets must be legible in black or dark-blue pen under SEAB’s published candidate instructions. Only one oval per multiple-choice question should be shaded, fully and firmly; more than one shaded oval is marked wrong. A child must not fold, tear, crumple, wet or make stray marks on the OAS. Calculators and printed or electronic dictionaries, including translation dictionaries, are prohibited for AEIS English and Mathematics tests. SEAB also specifies different mathematical instruments for different admission levels. Knowing the content matters, but so does presenting answers on the correct paper and following the instructions.

For a family travelling to the AEIS venue from Punggol or from overseas, “what to bring” is therefore more precise than “pens and pencils”. The child needs a valid printed Entry Proof, a photocopy of the passport biodata page for identity verification, appropriate stationery and instruments for the assigned level. The exact examination venue, test times and candidate index number are printed on the individual Entry Proof. This guide explains how to shade answers, how written-response working differs from an MCQ, how to organise the permitted stationery and how to practise exam mechanics using original examples without pretending that a home-made paper is an official AEIS examination.

Quick answers for examination day:

• OAS pencil: a 2B pencil for multiple-choice answer shading.
• One response: shade exactly one complete oval per MCQ question; erase an old answer completely before changing it.
• Written answer booklets: use legible black or dark-blue ink under the published instructions.
• Identification: printout of individual Entry Proof and photocopy of passport biodata page; the June 2025 instructions specifically say do not bring the hardcopy passport to the test hall.
• Calculator: not allowed; no printed or electronic dictionaries.
• Required Maths instruments: ruler for Primary 2–3; ruler, set square and protractor for Primary 4–5 and Secondary 1; add compasses for Secondary 2–3, under the published candidate table.
• Electronic devices: phones, smartwatches and other communication/computerised aids must not be used in the test.
• Timing: arrive at least 45 minutes before the paper; be seated at the assigned desk at least 15 minutes before it begins.
• Current instructions: SEAB AEIS/S-AEIS Instructions to Candidates (June 2025).

Editorial review: November 2026. Specific answer-sheet rules and instruments below come from the official AEIS/S-AEIS Instructions to Candidates updated June 2025, with test formats cross-checked against SEAB’s July 2026 test-details page. Read the instructions for your child’s actual examination exercise when they are issued; this independent guide does not overrule changed regulations or supply official OAS sheets.

1. What is the AEIS Optical Answer Sheet?

An Optical Answer Sheet is a separate answer document used for multiple-choice questions. Instead of writing the answer letter in the question booklet, a candidate shades the oval corresponding to the selected option. The sheet is personalised for the candidate under SEAB’s examination administration procedures, so it needs to be handled carefully and kept readable.

In the June 2025 candidate instructions, SEAB says the personalised OAS is issued with the question paper. The candidate shades answers using a 2B pencil. A shaded oval must be clear enough to be read, with no unnecessary marks elsewhere. Parents should not assume that ticking a box, circling a number or writing the answer beside the question produces a valid MCQ response.

Why the answer sheet is different from scratch working

A student may calculate a Maths answer in the question booklet and obtain the correct numerical value, yet lose the value of that MCQ if the wrong oval is shaded on the OAS. The Maths reasoning and answer-recording procedure are two separate skills. The child needs to do both accurately.

The OAS is not a place to show a complete algebra solution. Written working for short-answer and open-ended tasks belongs in the appropriate answer booklet. Understanding which paper records which type of answer can prevent errors that are unrelated to mathematical ability.

For Secondary English, the 50 compulsory comprehension and language-use MCQs also require accurate multiple-choice recording. A learner can misread the answer numbering when moving between a long passage and the OAS. Practise checking the printed question number without creating distracting rituals that consume valuable time.

2. Five rules for shading an AEIS MCQ answer

1. Read the question number. Match it to the corresponding numbered row on the OAS. Do not rely on memory of the previous question.
2. Choose one option. Decide from the mathematical or textual evidence before shading.
3. Shade one oval completely. Use the specified 2B pencil, with a firm, clear fill.
4. Erase fully if changing an answer. Use a soft eraser and remove the earlier marking completely before shading the new oval.
5. Keep the paper intact. Do not fold, staple, tear, wet or add stray markings to the OAS.

SEAB explicitly says multiple ovals shaded for one question will be marked wrong. It also says not to make unnecessary markings. The safest habit is therefore a clean, deliberate response rather than crossing out the oval, writing a new letter in the margin or drawing arrows between rows.

What if the child chooses the wrong option and wants to change it?

Changing an answer is not itself prohibited. The official instruction is to erase the original oval completely with a soft eraser, then shade only the new chosen option. A child should not leave two faintly or partially marked ovals. Practise the physical process with an ordinary home-made answer grid, but recognise that the actual OAS belongs to SEAB and should be handled only as instructed on the day.

What if the student skips a difficult question?

The student must take care not to shift the numbering when returning to an unanswered item. For example, if Question 8 is skipped and the learner shades the next answer on row 8 instead of row 9, all following answers may be misaligned. Ask the child to check the printed question number each time. This is an important procedural skill that can be learned without increasing academic stress.

3. Written-response work uses a different method

In the June 2025 candidate instructions, SEAB says candidates should write answers in the spaces provided using black or dark-blue pen and keep handwriting legible. They should not write answers in the left or right margins of the booklets. The candidate index number should be written on the cover page of all provided booklets as instructed.

For English composition, the instructions say that the candidate needs to write the question number, including an alpha character where relevant, but does not need to copy out the entire question. They direct candidates to leave a line between answers, write on both sides of the paper unless otherwise specified, not fold the writing paper and not divide pages into columns.

Mathematics short-answer and open-ended questions require appropriate working. The student should show the relationship between quantities and the method leading to the answer. A correct number without the required written method may fail to demonstrate the reasoning expected in the written component.

Clear mathematical working is not the same as excessive writing

Suppose the question asks: “Five identical books cost S$45. How much do three cost?” A clear method is: one book = 45 ÷ 5 = 9 dollars; three books = 3 × 9 = 27 dollars. There is no need to fill a page with unrelated calculations. The steps show the unit relationship and answer the precise question.

In a longer equation, each line should preserve equality. A student who writes 3x + 4 = 19, then x = 19 − 4, then x = 15 without dividing by three has lost the relationship. Training the child to label each step and check by substitution is more effective than memorising a method without understanding it.

4. Which Maths instruments does each AEIS level need?

The published candidate instructions include a table identifying the relevant mathematical instruments by admission level. The table helps parents avoid both omissions and unnecessary equipment. It is not a requirement to carry every mathematical tool available in a stationery shop.

The general stationery list also mentions pens, pencils, a sharpener and eraser. The June 2025 instructions say stationery should be kept in a clear plastic folder without English text labelling. Read the current exercise’s instructions before packing, because the authority may clarify item and container rules.

How much should students practise with these instruments?

A Primary 4 child should be able to use a ruler and protractor as taught at the preceding school level, while a Secondary 2 child may need accurate constructions and compass handling. The exact Mathematics syllabus determines which ideas are assessed. Familiarity with permitted tools reduces unnecessary friction but is no substitute for understanding geometry.

For example, a student may understand that an angle is 60° but place the protractor’s centre away from the vertex. The result is an incorrect reading even though the concept is known. Teach correct alignment, the appropriate scale and a visual reasonableness check. Then present a different angle without an adult demonstration in front of the student.

5. Entry Proof and passport photocopy: identity verification is precise

SEAB’s published AEIS test-details page requires a photocopy of the child’s passport biodata page and a photocopy of the Entry Proof, while the June 2025 candidate instructions specify a printout of Entry Proof and photocopy of the passport biodata page. The detailed instructions explicitly tell candidates not to bring the hardcopy passport to the test hall. Parents should follow the actual current exercise’s requirements and handle original travel documents separately.

Do not write anything on the Entry Proof or passport photocopy. The candidate should place those documents on the desk for verification as directed. The Entry Proof states the candidate index, admission level, schedule and venue. Keep it legible and complete.

AEIS Entry Proof is not permission to enter Singapore from overseas. ICA travel requirements are separate, and families must not assume that the school-entry test grants an immigration visa. A passport needed for cross-border travel may have to be handled by the accompanying adult outside the examination hall under current venue instructions.

Parent access is not automatic

The June 2025 instructions say parents or guardians are not allowed into the test venue during reporting. At dismissal, one adult per primary candidate is allowed into the waiting area under the specified arrangement. Parents should check the actual published supervision and dismissal instructions for their exercise, especially when several siblings are sitting different levels.

A child should know how to follow directions from invigilators and which adult will collect them. The family’s designated pickup plan should not depend on a parent being allowed to accompany the child all the way to the assigned examination desk.

6. Calculators, dictionaries, phones and smart devices

SEAB prohibits calculators and printed or electronic dictionaries for AEIS English and Mathematics under the published rules. This includes translation dictionaries. A student may be accustomed to using a calculator during normal overseas lessons; that habit must be adjusted for the actual admissions-paper conditions.

Electronic and communication devices are also restricted. The instructions mention devices such as mobile phones and smartwatches that can store or display information. Candidates must switch off prohibited communication devices and follow the venue’s storage instructions. Do not assume a smart watch is permitted as a simple timepiece because the student promises not to open its apps.

Seemingly harmless paper notes can also create problems. SEAB prohibits unauthorised references and notes in the hall and prohibits removing examination question papers or used/unused writing paper from the venue. Parents should teach the child to follow the invigilator’s instructions rather than treating official papers as souvenirs.

What if a device rings during the test?

The candidate instructions state that devices producing ringing chimes during the exam will be removed immediately from the venue because they disturb other candidates. The safest approach is not to bring unnecessary electronic items into the test environment. Read the current regulation and follow the official storage directions.

A learner should not be made responsible for negotiating an exception based on a parent’s convenience. If there is a genuine individual accessibility or medical concern, raise it through the proper authority before the test rather than assume an invigilator can approve any device spontaneously.

7. Ten original OAS, working and stationery practice situations

These are original procedural learning examples, not copies of the official OAS or official examination questions. Parents can use ordinary blank paper to teach the principle, then rely on SEAB’s current instructions and materials on the actual test day.

Situation 1: two ovals are shaded

A student decides Question 5 is option ②, then changes their mind to ③ and shades ③ without erasing ②. Under SEAB’s instructions, more than one shaded oval for a question is marked wrong. The correction is to remove the first shading completely with a soft eraser and clearly fill the final chosen oval.

Situation 2: the answer is correct but shaded on the next row

The learner solves Question 12 correctly but shades row 13. The Mathematics is not the problem; answer-sheet alignment is. Teach a simple check: say the question number silently, locate that row and confirm the option before moving to the next question.

Situation 3: the student circles the answer in the booklet only

A child circles option D beside a multiple-choice problem but leaves the OAS blank. The official multiple-choice response is recorded on the OAS. Practise distinguishing working done on the question page from the final response that must appear on the correct sheet.

Situation 4: an eraser leaves a faint second mark

The candidate erases the old option incompletely. Train careful erasure and clean shading during practice. Do not make random extra marks in an attempt to show invigilators which one is intended.

Situation 5: a child uses a ballpoint pen on the OAS

The published instructions require 2B pencil for OAS shading. A black pen may seem darker, but it is not the specified medium. Parents can pack a suitable pencil and eraser separately from the black/dark-blue pen used for written booklets.

Situation 6: a short-answer Maths method is missing

Question: 4 identical packets cost S$28. What do 7 packets cost? The final answer is S$49, but the written method should show one packet costs 28 ÷ 4 = 7 dollars, then seven cost 7 × 7 = 49. This is clear and efficient, not unnecessarily long.

Situation 7: an algebra error before final answer

Question: Solve 5x − 8 = 27. Add eight to both sides to obtain 5x = 35; divide by five to obtain x = 7. Check that 35 − 8 = 27. If the student writes x = 35, the missing division reveals the first unstable step.

Situation 8: the wrong protractor scale is read

For an angle opening to the right, a student uses a scale that begins from the opposite end and reports 120° instead of 60°. Teach choosing the correct starting ray and scale. A basic sketch can often confirm whether the angle should be acute or obtuse before reading a number.

Situation 9: the composition question number is omitted

A Secondary candidate begins an English composition without writing the relevant question number. The published candidate instructions explicitly require the question number, including the alpha character where applicable. Practise reading all instructions and identifying the chosen prompt before writing.

Situation 10: calculator habit blocks a simple arithmetic check

The child solves 18 × 5 by reaching for a calculator. Under AEIS it is not permitted. Teach a reliable no-calculator method: 18 × 5 = (20 − 2) × 5 = 100 − 10 = 90, then compare with repeated addition or another calculation. The goal is number reasoning, not just speed.

After every situation, give a changed example to check independent transfer. A student who understands the correction only while the adult points to the correct OAS row needs more procedural practice before the exam day.

8. How question timing interacts with answer-sheet accuracy

Under SEAB’s published AEIS structure, Primary 2/3 Mathematics Part 1 has 29 MCQs in 25 minutes, while Primary 4/5 Part 1 has 30 MCQs in 35 minutes. Secondary Mathematics Part 1 has 34 MCQs in 30 minutes. Those parts leave limited time for indecision or repeated answer-sheet mistakes.

These are examination-part totals, not recommended time allocations for every question. Some items require more thinking than others. A student should learn to recognise when an approach is failing, move on appropriately and return if permitted by the paper’s instructions and remaining time.

For English, the Secondary paper includes composition and 50 language/comprehension MCQs. The child should practise choosing a composition topic and organising the answer before writing. The exact paper instructions control timing; do not invent a universal rigid split that guarantees full marks.

A checking routine that does not consume the whole paper

Check the question number and answer row as you work. Leave time for a final quick review of unanswered questions and potential misalignment. In written Maths, read the requested quantity and units. For composition, verify the chosen topic and essential content. Checking is not a ritual of rereading every sentence repeatedly; it is a targeted response to likely errors.

9. Why handwriting matters but perfect calligraphy does not

SEAB asks for legible written answers. The purpose is to make reasoning and words readable. A student should form numerals clearly, distinguish a 1 from a 7, and avoid writing multiple conflicting final answers without clarifying which is intended. The school may teach particular working conventions, but neatness should serve meaning rather than become a separate source of anxiety.

A learner who writes very slowly may benefit from practising concise, correct working under realistic conditions. However, the family should not promise any official extra writing time without an actual AEIS-specific approval. The existence of access-arrangement policies for other national examinations does not establish identical AEIS provisions.

Use short bursts of clear writing and independent problem solving. If a student has a genuine functional disability or learning need, contact the examining authority early about the correct process rather than rely solely on a parent’s estimate.

10. An evening-before packing checklist

1. Read the actual exercise’s current Instructions to Candidates and the child’s Entry Proof.
2. Confirm the exact test venue, start time and reporting time.
3. Print Entry Proof and prepare the required passport biodata photocopy.
4. Check a working 2B pencil, an eraser and sharpener.
5. Pack a black or dark-blue pen for appropriate written answers.
6. Add a ruler and only those other Maths instruments specified for the entry level.
7. Use the permitted clear stationery holder described by the current candidate instructions.
8. Leave unauthorised notes, calculators and dictionaries out of the test materials.
9. Plan the handling of phones, smartwatches and other devices according to the rules.
10. Organise safe travel, adult collection where required, rest and breakfast.

Parents should pack based on the actual year’s rules, not solely on a photograph of another person’s stationery from social media. A good exam kit makes administrative requirements easy; it does not compensate for unfamiliar Maths concepts or weak English comprehension.
