Hi Vicky.

Accoding to the rules of Thapar University, you have to attempt JEE Main and score 20% or 15% in JEE mains with a minimum of 60% and 80% marks in 12th - (Physics and maths are compulsory). So, I don't think you can take admission into Thapar university directly, without JEE main. and also, the last date of application is today. Refer this link for more details -

Good Luck.
