WANTED: YOUR WEAK SPOTS
BEFORE YOU SET SAIL
- Questions mix every sub-topic together — Counting Principle, Permutations, Combinations, Circular Arrangements, Restrictions, and Probability — just like they'll appear on a real test.
- Difficulty rises gradually from East Blue (easy) to Raftel (hardest).
- Tap Hint if you're stuck. Every question also unlocks a short Concept note after you answer.
- Right answer = confetti. Either way, the explanation appears immediately below.
- Use the Print Booklet button anytime for an ink-friendly PDF with an answer key on the last page.
