Hi Amit,
1. If you want to Pursue B.tech in NIT's give JEE Exam and If you want to Pursue B.tech in IIT's then JEE Advanced exam and B.tech is not there in BITS but you can do B.E by giving BITSAT Exam.
2. If you want to Pursue B.tech in other Colleges give EAMCET Exam and other exams conducted by Colleges ( for example SRM University intake Students by conducting Exam)
3. If you have low JEE Score and didn't get admission in any NIT then Some Engineering Colleges give admission to you based on their the actual entrance exam cutoff of the College.
4. If you didn't give any of the above exams and want to B.tech then you can directly get admission under management quota or something but make sure that Particular College you are applying is Good at Placements and faculty.
Let me know your current location.
Hope it helps. Inbox me if you have any queries.
