The marks scored in BITSAT doesn't matter for scholarship in Indian campuses of BITS-Pilani. For Dubai Campus, scoring above 300 would be sufficient for 75% scholarship.

Also, for MCN Scholarship, CGPA has to be greater than 8.5 for 80%, between 7.5 and 8.5 for 40% and greater than 6 for 25%.

Actually, it is not necessary, but you must be thorough with the important and frequently asked chapters. If you have a previous year questions, then refer it.
As time is very less, you just concentrate on the topics which you are confident and strong. If you want to read new chapters (if you wish to) then, complete those within a maximum of 5-7 days, because BITSAT requires more practice.
That's why, give some time to English vocabulary and logical reasoning, because they have a total weightage of more than 20 questions.
So, focus on what you do, aim to score 300+.
All the best.
