Bulk distribution of uncorrected PDF copies (without grades or the word "correction")

As a teacher, I would like to be able to send students their exam papers as PDFs immediately after the exam, even before they have been graded. Currently, the PDF export automatically includes a score (0/20) and the word "correction," which is not ideal for a simple review. I want to be able to send these "raw" copies in bulk so that students can review their work immediately.
