Biology

Hello Anannya,
Firstly, you have to clear the backlogs before you can think of admission in any college. Secondly, I would like to advise you to get out of the obsession with engineering. Try some other subject which interests you.

Muskan,
For a career in banking after class 12th (PCB), you can go for courses like BBA, BBA (Hons), BBA-MBA, etc.
These courses are going to equip you with the theoretical and practical aspects of business and managerial skills. After the course from a good university, you can get a placement in a good private bank or you can prepare for some bank papers and cracking them to become a part of some good govt. bank.
There are many good govt. and private universities like IIM, Indore; GGSIU, Delhi, LPU, Punjab; GU, Visakhapatnam, etc., that are offering these courses with good placements.
Check their websites for more details.
Good luck.

Here are some of the subjects which will be there in B.Sc course for the bio candidates:
Physics
Chemistry
Electronics
Statistics
Botany
Zoology
Biotechnology
Microbiology
Genetics

Hello Shivani,
I feel it's the best option you have thought of choosing. In the days to come, biotech will be the field giving max employment. Have no hesitation.

If you have selected computer subject in your 12th then you have a chance to do B.Sc in computer science.

Hello Shivangi,
Admissions to 12th are not controlled by state but eligibility is decided by the university. For B.Sc in biotechnology, bio is desirable but not mandatory in 12th.

Of course, you can. I'd advise you check out the cut-offs for the college you want to join.
