​
Limits and notes

  • A batch scan is one PDF, up to 250 MB, holding every student’s pages in order.
  • Not available for video and audio assignments.
  • Every submission the split produces counts toward your monthly limit.

​
Before you start

Scan the stack as one PDF with each student’s pages together and in order. Blank separator pages are fine; you can skip them afterwards. Scan at a normal resolution so the file stays under 250 MB.

​
Upload and split

1

Open the upload dialog

On the assignment’s Submissions tab, select Upload submission. In Instant setup, the same choice sits in 4. Student submissions, where a hotspot asks “Scanned a stack of work at once?”.
2

Choose Batch Scan

Select Batch Scan: “One PDF with multiple students’ work — we’ll split it into a submission per student.” In Instant setup the control reads Separate files / Batch Scan.
3

Add the PDF

Drop the one PDF in, or select Your device or Google Drive. The dialog confirms “We’ll detect each student and create separate submissions.”
4

Upload & split

Select Upload & split. The Match submissions screen opens and reads “Reading your scan to find where each student’s work begins — this can take a minute…”.
5

Check the split

Each proposed submission shows its page range, the name GradingPal detected, and a confidence pill. Rows that look off carry a Fix pages button and an amber note. Choose the right student on any row that says Needs student.
6

Confirm

Select Confirm & grade N. A toast says N submissions added — grading started, and every row on the Submissions tab moves to AI grading.

​
When the split lands in the wrong place

Select Adjust pages. The scan opens as a board of numbered submissions, Sub 1, Sub 2 and so on, each holding its pages. Drag a page to the submission it belongs to, select Add submission to start a new one, or use the skip control on a blank separator page. Select Done to return to the list. Re-split throws the split away and reads the whole scan again. If you’ve made page or student changes, it asks first: “This re-reads the whole scan and replaces your manual page and student changes with a fresh split.”

​
How to tell it worked

The summary line above the list reads N of N ready with nothing after it. Once you confirm, the Submissions tab shows one row per student, all in AI grading, then Needs review.

​
If something goes wrong

“A batch scan must be a single PDF” means you added a second file or a non-PDF. “A batch scan must be under 250 MB” means the scan is too big; rescan at a lower resolution or split the stack in two.
The banner says so. Open Adjust pages and drag those pages onto a student, or skip them if they’re blank.
The row says “Also assigned to” the other file. Pick a different student on one of them; Confirm & grade stays greyed out until you do.
The scan stays uploaded, but the split is discarded. Open it again and the split runs from scratch.
Opens GradingPal on the screen this page describes.
