In case you are interested in a Bsc Physics course then Jee Main rank won't help. First you will have to be specific with the colleges you are aiming at. Because for Bsc Physics some might take through an entrance test and others might take through merit. Like Delhi University takes through Merit.

Have you given any entrance for the same course?

Some of the colleges which provide Bsc in Physics are:

DU colleges

Amity university

LPU

KR Managalam

St Stephen College

Based on your interest you can apply for the same.

Good Luck.
