Hello Sanjay Kumar. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

Please note that around 1.5 lakh students wrote BITSAT every year for just 2000 seats across the three BITS campuses, in Pilani, Goa and Hyderabad! See the intense competition.

So, if you want to get a seat in BITS, the level of input you should put into your preparation should be quite high.

Please see this blog for more information about the same:

Hope this helps you and all the best!
