If a Punggol student can enter SLS but cannot open an attached Google file, check which Google or iCON account is linked to the student’s profile. Access denied can involve account selection or file permissions; it does not always mean the SLS password is wrong.
The official SLS account route is the right menu, Edit Profile, then Manage Linked Account under Account Settings. Compare the displayed email with the account the teacher expects your child to use before changing anything.
For a teacher-attached Google answer file, use the assignment’s Open in New Tab or Edit control. SLS creates a personal copy with the student’s name at the beginning of the filename. Work in that assigned copy and return to SLS to submit it.

Open the student’s assigned copy
CHAPTER 1 OF 5
Separate login trouble from file trouble
First check whether the student can open the SLS lesson itself. If SLS login fails, resolve that problem before investigating Google permissions. If the lesson opens but one attachment fails, record the attachment name and exact error.
Notice whether every Google attachment fails or only one. This is a useful troubleshooting comparison, not proof of the cause. A teacher may need to check a particular file or assignment.
CHAPTER 2 OF 5
Check the linked account
Follow the official Manage Linked Account guide. Its linking process uses Sign in with Google, the chosen account and permission checkboxes allowing ufinity.com access to Google Drive files; a successful link displays the email.
On a shared family computer, check the active Google identity as well. A parent’s personal Gmail account may be open in another tab. If the linked email is unexpected, ask the teacher which account is required before unlinking or switching it.
CHAPTER 3 OF 5
Open the student’s assigned copy
The official Google-attached file instructions explain that the personal copy can be edited in Google. After completing it, return to SLS and submit the file for marking.
Check that you are working in the copy opened from the assignment. Making an unrelated document in a separate Drive folder can create confusion about which version the teacher will receive.
CHAPTER 4 OF 5
Handle access denied without losing work
Save any accessible work before trying changes. Note the Google email shown, lesson title, file title and error message. Send the details through the school’s usual channel, with a screenshot if useful.
Ask the teacher to confirm the expected account and attachment access. Repeatedly requesting access from different family accounts or creating replacement copies can make the problem harder to trace. Avoid sharing passwords with the error report.
CHAPTER 5 OF 5
Check submission and corrections
Editing the Google document and submitting the SLS answer are separate actions. The official guide states that the Google file cannot be edited once submitted. For corrections after feedback, it describes editing a copy under Teacher Comments.
Before a deadline, verify the assignment’s submission state. If it remains unfinished because access is blocked, inform the teacher while the problem is being investigated and ask how to provide the completed work.
