Hello Sneha,

As you have mentioned that your JEE mains percentile is 80.You have not qualified to appear for JEE Advance.And you won't be having a chance to get in to any of the NITs if you just belong to general category.Hence it would be highly recommended if you join some other colleges which give you admission based on other entrance examinations.Hence you can go for other private colleges like BITS and give BITSAT.And it is said that the computer science branch in BITS is equally good as top IITs.
