I got 84 percentile in JEE Mains 2019. Can I get a seat in Osmania or JNTU via JEE Mains percentile or ranking?

If candidates have identical Common Rank List (CRL) in JEE (Main) - 2026 Paper-I even after applying NTA's tie-breaking measures, the following order of additional tie-breaking criteria shall be adopted for seat allocation in JAC Delhi:
1. Date of Birth (preference to the elder candidate).
2

Candidates wishing to take admission in BTech at Ramaiah Institute of Science and Management have to appear in JEE Main, JEE Advanced, CUET-UG, SAT, KCET, COMEDK. So, yes even if you have not appeared in JEE, you can produce score card of any of the above mentioned exams. 

The East Point Group of Institutions accepts many exams for the BE course. The accepted exams are JEE Main, COMEDK, and KCET. Students can appear in any of these exams to get admission at EPGI. Students need to fulfil the eligibility criteria as well.

Amrut Institute offer admission in BTech and Diploma in Engineering based on merit in last qualifying exam. So, no JEE Main is not compulsory to take admission in Amrut Institute courses. 

With 57.8 percentile in JEE Main and 73% boards, getting CSE/AI in top government colleges is unlikely. But you still have good chances in private colleges through UPTAC/AKTU or direct admission.

Possible options:

KIET Group of Institutions

ABES Engineering College

Galgotias Coll
