Hi Mayuri,

For admission in SRM Chennai, SRMJEE is conducted every year, but due to pandemic, SRMJEE has been canceled this year. With SRMJEEE 2020 compensated, the SRMIST will conduct the admission based on 10+2/Pre-University/Equivalent marks and JEE (Main)/SAT Score. It will be right now difficult to say that with 81 percentile in JEE Mains, will you get SRM Chennai or not.

Anyway, I will suggest you visit this link for clarity over JEE Main college predictor - https://engineering.careers360.com/jee-main-college-predictor?icn=jee-main-cp-lp&ici=nav-header_engg

All the best.
