No. Of correct attemts including all 3 sections (QA,VA,LRDI) 38-45Range. What should be the expected CAT percentile ?

See there is no surity of what percentile you can get with any number of correct questions because it is a relative phenomenon which aling with your performance also depends on the performance of other students appearing for exam. That's why itbkeeps changing every year. It also depends on the difficulty of paper. If it's easy then even after fetching a good score you might not end up with a good percentile whereas if it's difficult then even with low marks you can end up with high percentile. As I said earlier it's all relative with your peer group.

If I tell you on General basis seeing your range of score by the correct attempts and assuming 80-90% accuracy your score will lie in the range of 110 - 130. In this score generally you can score around 83-88 percentile. But as I said it's all relative so don't focus on it.

Other than that as very less time is left so you need to brush up on your basics and give up lots of online mock test abd analyse each of the test's solutions which will help you in overcoming your mistakes and come up with a strategy to attempt your paper which will definitely help you in improving your marks and percentile.

With online mock test you can also get a better predicted percentile through your score. But don't rely on that also as it is all relative and changes every year.

All the best for your preparations and exams!!
