Hello aspirant, as you are in 11 th standard you have enough time to get CSE in IIT BOMBAY.Since it is the top one institution so getting admission in this college have cut throat competition. There is only around  15 seats reserved for scheduled caste .You have to study very hard and be strongly determine to get in. You should be  clear concepts and should strong grasp on it.Clearing advanced is all about speed and accuracy .

Rank for IIT B vary  every year so it is hard to predict .

Good luck for your future.
