WBJEE

During WBJEE counselling, only your WBJEE rank and your total percentage of class 12th boards is considered. Your maths marks will not be considered individually.

No, you need to appear for WBJEE to pursue B.Tech (4 years) in any branch in MAKAUT University.

Hi Anisha,
Unfortunately, admission in Indian Institute of Aeronautical Science is not available through WBJEE score. You need to take the IIAE entrance exam to get into this institute.

You can get WBJEE previous year question papers from the official site:
https://wbjeeb.nic.in/WBJEECMS/Public/View.aspx?page=93
You can also buy a book of 10 years solved WBJEE questions papers published by Arihant or any other publisher.

For government colleges (except Jadavpur University), you need to score 45% in class 12th, for general category, and 40% for reserved category candidate. But, you will get a lot of private engineering Colleges.

Budge Institute of Technology will be better.

No problem, OBC - A means general only and OBC - B means you will get benefit of OBC. So, if you fill it by mistake, then they will treat you as general. They will not reject your admission. So no need to worry.
