Doing papers is the highest-leverage revision there is — if you do them right. Here's a simple loop that works.
Most students download a stack of papers and then… stare at them. The papers aren't the point — the loop you run on each one is.
Step one: do a paper under timed conditions, no notes. This is uncomfortable, and that's exactly why it works — it mirrors the real exam and shows you what you actually know.
Step two: mark it honestly against the mark scheme. Don't award yourself “half marks for trying”. Note every place you lost a mark and why.
Step three: for each lost mark, find the method. This is where worked solutions and the AI tutor earn their keep — they explain the how, so the same mistake doesn't cost you twice.
Step four: re-do only the questions you got wrong, a few days later. Spaced repetition on your weak spots beats re-reading the whole topic.
Run that loop on two papers a week and your grade trend will climb. SuperExam tracks that trend for you, against the real boundaries.
