Wrong answer mode can be used on over 90% of our courses.
Due to the way we make our courses on some special sessions wrong answers mode isn't available.
This happens when it's important for you to see a set of questions one after another for them to make sense.
During a predicted paper, it wouldn't make sense to see question 2 before question 1!
When Wrong Answer mode unavailable, it's best to select an 'Adaptive' learning session.
