As per your background, I would suggest you opt for M.Sc in Biotechnology, whereas, it completely depends upon your interest. I have one of my classmate who did Bachelors in Biotechnology with me and then moved on for Mass communication for Master's degree because of his interest.

Which subjects are you interested in?

Yes, it is necessary for M.Sc to get a degree in the same subject. So, if you want to do M.Sc in botany you have to do B.Sc in the same.

You can check with the college as of now. Graduation admissions have begun but for PG, you can check the college website.

You can get the previous years papers from Shamshad market in Aligarh (in case you are in Aligarh) or you can get it couriered to your location from the nearest market.

It is very common among candidates that they are unknown to the way of a proper study. Most of the candidates don't know which subject they have to study and for how much duration, which is the scoring section, negative marking scheme, etc. Somewhere, it is also very important for the candidates to know their whole exam pattern prescribed by the official authority.

See, to be clear you can't manage both B.Sc and NEET together.
There is a saying that do not put each foot on different boats. So I suggest that do not mess up with 2 different courses. Just be clear about what is your goal, it is either B.Sc or getting MBBS through NEET. But remember one thing, you should be confident about what you want to choose. Your goal should be clear.
