WBJEE

With 75,000 rank, you can get private colleges like Dr. Sudhir, Guru Nanak, JIS college, Durgapur College of Engineering and Management, BBIT, etc. All these colleges are same. What I will advice you is that either you go for private external counselling or choose the college from above list which is near to your house.

If you want computer science branch then the best colleges which you can get are Techno India-Rajarhat, BPPIMT, Future Institute-Sonpur, and MCKV. If you choose other branches then you can get IT in RCCIT which is a good choice again.
Feel free to ask your questions.

Very few seats are available in colleges for OBC category though WBJEE. As your OBC rank is 976, you can get government colleges like MAKAUT, JGEC and few more in the first round. As far as private colleges are concerned, you can get any course in RCCIT. Choose your college wisely, ask an expert on Sikhsha if you have any difficulty.

You may get some good colleges but not sure that it would be a govt college. With this rank, your ward may opt for the desired branch in some college of West Bengal.

Hi,
It's difficult to get a good college with this rank as most of the colleges prefer a rank below 10,000. You may get a college but I am not sure about the desired branch. You can try for some colleges like IEM and UEM, Bengal College of Engineering, etc.
