Volume of practice matters less than how you review your mistakes. Here's a better approach for IB Math students.
Grinding through dozens of practice problems feels productive, but many students plateau because they never fix the actual gaps in their understanding — they just repeat the same mistakes faster.
The mistake log
Keep a running log of every question you get wrong, categorized by why you got it wrong: careless error, misunderstood concept, didn't recognize the question type, or ran out of time. Patterns emerge fast.
Recognizing question types over memorizing steps
IB Math AA and AI both reward pattern recognition — knowing which technique a question is testing before you start solving. Instead of memorizing procedures, practice identifying "this is a related rates problem" or "this is asking for a definite integral in disguise."
Redo problems a week later
Don't just move on after correcting a mistake. Come back to that exact problem type a week later without looking at your notes — this is where real mastery is tested.
Use the mark scheme as a teacher
Past paper mark schemes reveal exactly how examiners award method marks. Study them as carefully as you study the questions themselves.
More practice helps, but only when paired with deliberate review. Quality of reflection beats quantity of repetition every time.
