Short Additional Mathematics self-tests are one of the simplest ways to find out whether learning survives without notes, worked examples or immediate answer checking. A good self-test is not a giant exam paper. It is a small, deliberately constructed set that asks the student to retrieve, choose and execute methods independently.

This is useful between school assessments because it gives faster feedback than waiting for the next WA. It also exposes the gap between “I understand this when I see it” and “I can produce it from a blank page.”

At eduKate Punggol, Mathematics tutorials are held at 83 Punggol Central, Singapore 828761, near Punggol MRT and Waterway Point, in small groups of up to three students. Short self-tests can be built from current topics, older weak links and one changed-surface challenge.

The five-question self-test

• Question 1: one old-topic retrieval question.
• Question 2: one current standard question.
• Question 3: one changed-surface version.
• Question 4: one mixed-topic question.
• Question 5: one timed or slightly harder question.

Close the notes before starting

The purpose is to measure what can be generated independently. Notes can be opened after the test during marking and repair.

Delay answer checking

Do not look at the answer after every question. Finish the whole short set first. Immediate checking can leak cues into later questions and make the test less diagnostic.

Use fresh questions

If the student remembers the exact worked solution, the test may measure memory of the page rather than transfer. Change numbers, wording, diagram orientation or target.

Mix at least two topics

A short self-test should eventually include one question where the chapter is not named. This checks whether the student can select the method rather than merely execute it.

Use a small time limit only when appropriate

Timing should come after basic independence. A student still learning the method needs clean retrieval first; a student preparing for exams needs to know whether the method survives a clock.

Mark by first wrong step

The score is useful, but the first wrong step is more useful. Classify whether the error came from retrieval, method selection, Algebra, domain, working, timing or interpretation.

The self-test record

• Date.
• Topics included.
• Score.
• Questions not started.
• First wrong-step mechanisms.
• Hints used.
• Retest date.

Retest the failed mechanism, not the same paper only

If a self-test exposes a logarithm-domain failure, repair the rule and then use a fresh logarithm question several days later. The goal is mechanism change, not memorising the original set.

Build one self-test per week

For many students, a short weekly set is enough to detect forgetting early. It can take 20–40 minutes depending on difficulty and stage.

The 20-minute version

1. 3 minutes: two retrieval prompts.
2. 10 minutes: three questions.
3. 5 minutes: marking and classification.
4. 2 minutes: schedule one retest.

The 40-minute version

1. 5 minutes: retrieval.
2. 20 minutes: four mixed questions.
3. 10 minutes: one timed challenge.
4. 5 minutes: marking and repair plan.

What not to do

• Use the exact same worksheet questions every week.
• Check answers after every line.
• Choose only the student’s favourite topics.
• Make every self-test a full paper.
• Ignore questions left blank.
• Record only the score.

How to know self-testing is working

• Old topics remain available longer.
• Blank starts fall.
• The student needs fewer notes between lessons.
• Weak mechanisms are discovered before school tests.
• Changed-surface performance improves.
• Revision becomes more targeted.

A short self-test should create clean evidence: what the student can retrieve, where method selection fails, and what should be repaired next. Closed-book first, delayed marking second, fresh retest later.
