How we teach
Learn it, don't memorise it. Five habits do most of the work.
Answer first
You try each question before you see the explanation. Pulling an answer from memory, even a wrong one, helps it stick more than rereading.
Mistakes come back
Questions you miss or guess return after 1 day, then 3, 7 and 14. They leave once you get them right on two separate days.
Mixed practice
Practice sets mix content areas, so you learn to tell similar ideas apart.
Why wrong answers are wrong
After a set, a quick check asks why one wrong option is wrong. Knowing why is what carries over to new questions.
Know where you're sure and wrong
You say how sure you are. Confident mistakes are the dangerous ones, so they come back first.
