How many documents can I unlock per month on Course Hero?

For every paid membership option, you'll get 30 Unlocks per month, starting on your subscription date. Your Unlocks will refresh every month from the original registration date, and unused Unlocks don’t carry over. You may purchase additional Unlocks once you run out, as long as you have a Premier Membership.

If you receive Unlocks from uploading your documents, they'll expire 30 days after you receive them.

Course Hero does not offer unlimited unlocks.
