Biology

You can do MBBS or Engineering in Biomedical or Biotechnology. Or, go with B.Sc courses which have Biology as a subject.

There is no fixed number of students applying for BITSAT with Biology as the subject. The number keeps on varying year on year. I can tell you one thing that no doubt the competition is high, but if you are clear with your concepts and determined, you can surely get a call for admissions.

Yes, you can pursue a course related to pharmacy field.

Delhi University, IPU and some private universities like Amity University are the good options to pursue B.Sc.

If you have good grades in 12th, you will easily get admission there. Just calculate your best 4 and check whether you are eligible for the courses by seeing the cut-off on the DU official website (or check if any entrance test is there for the courses you have mentioned, on the official website of DU).
The fee is very less since they are government colleges.

You can opt for this course without any problem, it will include coding. So, if you are having interest and coding then it is a very good choice for you.

As you are not having maths in your 12th so you cannot apply for B.Tech but you can go for other courses like biotechnology, pharmacy, medical and many more.

You have many choices after class 12th:
MBBS,
BDS
Veterinary
BAMS
BHMS
B.Sc AG-ICAR
B.Pharm,
Pharm.D,
BE in Environmental Engineering,
BPT (Bachelor of Sciences or Forensic Sciences)
B.Sc in Zoology, Microbiology, Nursing, Paramedical courses B.Sc in geology, biochemistry, pathology, radiology and speech therapy occupational therapy.
You can also do other courses like hotel management, BBA, etc.
It is depended upon you as which course you are likely to join. This is the turning point in your life. You are the only one who can make your future bright. Choices are many but select the one which satisfies you.

Check with your college or university scholarships. Additionally, some universities offer automatic merit-based scholarships based on your grades. For example, BYU-Idaho offers scholarships for current college students you have at least a 3.75 GPA. The higher your GPA, the more tuition the school will cover.

It is not possible for a biology students to take admission in bio medical engineering . With biology you should have to have mathematics as your one subject. Because bio -medical engineers are after all will deal with the calculations , so if you score good marks in your engineering entrance still you need to have Mathematics as your subject in Class 12th. However, you can pursue B.E (Bachelor of Engineering) in biotechnology. Good Luck Sayan.
