Hi deep

If you have not given your JEE exam, how can you take admission in West Bengal college according to JEE main score.No,it is not possible.

JEE main is the eligibility criteria for most of the colleges in India.You can get in college either through your +2 percentile or by the entrance exam of that college.

Hope you get your dream college.Wshing you luck for the future.
