How many documents can I unlock per month?

With a Premier Course Hero membership, you'll get 30 unlocks per month starting on your subscription date. This is the same for all our membership options. Your unlocks will refresh every month from the original registration date and unused unlocks don’t carry over. If you run out of unlocks, there's no need to worry! 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.
