1. The âImport from Google Driveâ button doesnât work
Refresh your browser and try again.
Make sure pop-ups are enabled for CoGrader. Googleâs authentication flow opens in a new window.
2. Youâre stuck at âContinue with Googleâ
Double-check youâre logged into the correct Google account.
If you're using multiple accounts, try logging out of the others or using an Incognito window.
3. Canât find your assignment folder in Google Drive
Navigate to Google Drive first to verify the folder exists and contains valid student files (PDF, JPG/PNG, or HTML).
Make sure files are in the supported formats.
4. Some files didnât upload
Check if the file type is supported. CoGrader only supports:
.pdf.jpg/.jpeg/.png.html
If a file wonât upload, try downloading it locally and re-uploading it manually.
5. The page freezes or wonât proceed to grading
Clear your browserâs cache and cookies, then reload the page.
Chrome works best with CoGrader. Try switching browsers if issues persist.
