Hello Harshika, with a rank of 1.5 lakh in JEE mains, it's difficult for you to get into any NIT or any GFTIs because the cutoff for addmision into these colleges are high if you are from general category. If you are interested and want to study engineering better try for some good private engineering colleges.

You can also use the college predictor tool to find colleges with your rank. The link is given below:
