Redpen

You buy credit, not a number of scripts.

Marking spends what that marking actually cost, plus our margin. A short paper costs less than a long one. Scripts sent together cost about half as much each as the same scripts sent one at a time.

Plans

Running low

Add credit at any time, from $20. Credit you buy outright rolls over and stays yours — including if you cancel the plan. Your monthly allowance is spent first, and what is left of it expires at renewal.

Send a class in one go. Ten or more scripts submitted together are marked as a batch, which costs us about half as much — and you are charged what it cost, so your credit goes about twice as far. Sending them one at a time is the expensive way to use Redpen.

Questions you would reasonably ask

Why not a price per script?
Because scripts do not cost the same. A 9709 Paper 3 is longer than a 2059 Paper 1, and a class sent together costs half a class sent separately. A flat price would mean charging everyone for the dearest case.
How do I know what I have spent?
Every charge appears in your account with what it was for and when. The app shows an estimate before you start and the exact figure after.
What are the numbers above, then?
A guide, not a promise — based on a typical script sent as part of a class set. Short papers go further; long ones less so.
What happens if a script fails to mark?
You are not charged for it. If you are charged for one that failed, tell us and we will refund it.

Opening to teachers shortly

Redpen is being tested with a small group of teachers first. If you mark Cambridge papers and want to be among them, write to us.
