1. Classify every miss
Put each mistake into one category: missing knowledge, misunderstood wording, incorrect setup, calculation error, weak evidence choice, or time pressure. “Careless” is not specific enough to fix.
2. Correct the process
Redo the problem without looking at the answer. Then explain why the correct method works and why your first method failed. If you cannot explain both, the skill is not secure yet.
3. Practice a small cluster
Complete several questions that use the same skill. Stop when you can recognize the setup and perform it consistently—not when you happen to get one right.
4. Mix the skill back in
After focused practice, return to a mixed set. Real test questions do not announce which rule to use, so recognition must become part of the skill.
5. Add timing last
Speed comes from cleaner decisions. Use a timer after accuracy improves. If timing causes accuracy to collapse, shorten the set and rebuild gradually.
