WBJEE

As per your rank, you should shortlist those colleges where the requirements match with your marks, then you can apply for those colleges. In the B.Tech career, the overall amount is 6-7 lacs for a 4-year course in the best colleges of engineering and technology. In my opinion, you can get admission in GITA BBSR college which is the best for you. The link for the college is:

Yes, you will get any campus of Techno India.
