Engineering Entrance Exam

Coaching for IIT-JEE is not just faculties and study materials. In fact these take a back-seat when you are really focussed on your goal. 90% of your success will be determined by the environment you're in, your peers, and the overall competition you're facing. Quality of lecturers or the extensiveness/exhaustiveness of study material are points pondered upon only by the naive. Why? Because if you want to better your performance, it's upto you.and only you. Get study material from outside sources (FIITJEE/Resonance etc), it doesn't matter. IIT-HOME has competitive faculty, enough to get you to the level where your rank will be decided by the effort you put in thereafter. The atmosphere is such, the competition so high, it will compel you to do your best. This is well-researched advice and most of the others will agree - You want to do your best? What you're looking for is the environment that'll make you do it. And, if you're looking for the environment, think twice before going anywhere except IIT-Home.
All the best.

Hello Venkata,
Although, JEE Mains and BITSAT have the same syllabus they are like two sides of the same coin. Means, though they have the same syllabus, there are different methods to clear each of them.
First, JEE demands more concept clarity and accuracy, but BITSAT demands speed and accuracy. So, you need to have a knowledge of how the questions are in BITSAT?
In JEE, you need to score only the cut-off marks in your category to get a college, but in BITSAT, you must score 300+ to get admission in any of the campuses and it is irrespective of your caste.
For all these, the best way is to solve the previous year questions as they will give you an idea of questions and their difficulty then take as many mock tests as possible. So that you can improve your speed and accuracy. As you have very less time, focus mainly on this. Aim to score 300+.
All the best.
