Weak Point Focus is the single most efficient way to raise your score, because it only shows you questions you haven't mastered.
How questions get there
- Automatically — any question you answer incorrectly is added to your weak-point set.
- Manually — tap the Flag button on any question (even one you got right) to mark it for review. Use this for anything that felt like a lucky guess.
Working them down
Flags persist until you remove them, so you can keep hammering a tough question until it sticks. Run Weak Point Focus regularly; as you answer correctly and unflag, the set shrinks — a satisfying, measurable sign you're getting test-ready.
