Review student submissions

Annotate a copy when adding highlights or comments. Rotate scanned pages before reviewing them and use OCR only when searchable text is useful. Keep the original submission so feedback changes are easy to distinguish.

Handle student information carefully

Class lists, grades, accommodations, and identifying information may be covered by school policy or law. Prefer browser-based processing where possible and follow your institution rules before using any online service with confidential records.

Frequently Asked Questions

Can I create separate student and answer-key PDFs?

Yes. Organize or extract the required pages into separate copies, then label each file clearly before sharing.

What is the best format for classroom distribution?

PDF is useful for consistent viewing and printing. Keep an editable Word or PowerPoint source when you expect to revise the material later.
