is topic test questions unlimited or they are till when you complete your level 4

This is how the topic tests work:

1. There are 4 levels for each topic. You start from Level 1.
2. Each test has 5 questions. If you get 80% or more accuracy, your level increases.
3. If you're an absolute genius, with just 20 questions (5 questions * 4 levels = 20), you'll complete the entire topic (hasn't happened ever).
4. Most people take around 30-50 questions (because they have to reattempt certain levels).
5. Once all 4 levels are done, it changes to "revision" where all your wrong/unattempted questions from IPMAT Indore comes! If there are no such questions, then nothing comes up.
