Hi Yashraj. You have a 9/9/9 profile, which makes your profile very good as compared to the average pool. Your chances from this point onwards will be decided by your performance in CAT and subsequent stages. To check the minimum percentile you need to aim for, visit this link:

Some students grasp a concept rather quickly, some need to study multiple times to get a hold of it. My advice would be to give a mock, see where you stand, and then start working accordingly. If you are enrolled in one of the batches, then stick to the tasks that are given to you daily.Know that one has sufficient time if one starts working hard from today itself. All the best.
