Managing Scans for Bubble Sheet Assignments

Why doesn't my assignment have a Manage Scans page? The Manage Scans page is only part of the workflow for instructor-uploaded assignments. This page will not appear in the assignment workflow for student-uploaded assignments.

In this guide:

Uploading Scans

Need guidance on scanning best practices? Check out our scanning tips.

  • Once you have your PDFs ready to upload, click Select PDF Files on the Manage Scans page.
  • Select your files and they will begin uploading. You can also drag and drop submissions directly onto the Manage Scans page. While you can upload a PDF for each student submission, it's recommended that you upload PDFs that contain multiple student submissions for faster processing.


Creating Submissions

Once the scans have been uploaded, Gradescope will create submissions based on the bubble sheet template.

  1. If Gradescope was able to break up the entire PDF into submissions, you’ll see a message that submissions were created automatically (see image below). You can click Show to double-check that everything was split correctly. A scan (or PDF) that was uploaded and automatically split into individual student submissions.
  2. If Gradescope was not able to break up the entire PDF into submissions, you’ll see a yellow error message above your uploaded file that says “Ready to Create Submissions (Unable to confidently auto-split)”. If you see that message...
    1. Click Show to expand the pages of your scanned PDF. Then scroll down until you find the pages that Gradescope couldn't split accurately. These pages will have yellow error messages above them.
    2. Hover over the thumbnails of the PDF pages in question. When it appears, click the magnifying glass icon to zoom in on each page and see what's causing the error (e.g., there was an extra page in their scanned submission).
    3. Reorder, split, or merge pages as needed (see next section). If you need to, you can also click the red X in the top left of a thumbnail to delete that page from the upload.
    4. Click the Create Submissions button when you're finished.

Rotating submissions

If Gradescope automatically split your scans and you need to rotate a page, a submission, or all submissions in your batch, first, select the Undo Automatic Split button at the bottom of the page. If Gradescope did not auto-split your submissions, you will already be able to rotate pages.

  • To rotate a submission, find the submission, and click Rotate Submission to the right of it. Keep clicking until the submission is oriented correctly.
  • To rotate all pages in all submissions, scroll to the bottom of the Manage Scans page and click the Rotate PDF button.
