Often, candidates are required to qualify an institute, State or national-level entrance test for admission to the course.

Hi Kolle,
For getting admission in BITS Pilani, Hyderabad campus, you need to appear for BITSAT, and score well in the exam to secure a seat. However, for direct admission, you need to be a board topper. Best Wishes.

IBS Hyderabad has 1000+ students per batch which make placement difficult for students.
whereas XIME has a limited number of seats that is 120 per batch.
For marketing, both of these colleges are good but you need to consider various other factors such as batch strength, ROI, Fees, etc.

Sorry for saying this, there is no chance for you to get a seat in SASTRA in stream 2 based on your rank. Last year, students who got even 984 marks didn't get the seat. Try for other universities.

For that, you have to apply for the MHCET paper and then on the basis of that rank, you will be able to get admission in COEP.

IBS-Hyderabad is the best options. Go for it. Take the IBSAT Exam.
Hope you get it.

With PCB, you cannot pursue B.Tech as eligibility for B.Tech is PCM and maths is a compulsory subject. Without maths, you will not be able to pursue B.Tech. If you appeared for maths exam also in class 12th board then only you can pursue B.Tech.

Write any of the tests such as CAT /MAT /ATMA and send your scores to the college. If your scores are valid, you will be called for group discussion, and then a personal interview is done. If you have done well in all these rounds, you are selected.

If you are really interested in a better future and placements, then Instead of Hyderabad Try for SIMC Pune and Bengaluru. They provide excellent Placements with decent ROI. Best regards.
