No, to study pharmacy you need to study PCMB in 12th standard.

Yes, you can pursue B.Pharm course after qualify its entrance exam in 2017.

You can opt for any specialization. In my opinion, pursue MBA because MBA gives you better future ,in terms of the job opportunities. You will earn better after completing MBA.

The Bachelor in Physiotherapy (BPT) is the science of body movement. Biotechnology is the exploitation of biological processes for industrial & other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, & many other.
Both are equally best courses. You have to choose according to your interest only. If you have a broad vision & passion to work in different areas then Biotechnology will suit you. If you have a personality to work from your place, then go for BPT. Both have a good scope in the future.

According to me, BHMS is a better option.
After the completion of BHMS, you may find employment as:
-Homeopathic practitioner in both India and abroad.
-Medical representative at a private or government hospital.
-Professor or a researcher in any homeopathic college.
-You may start personal clinic.
-You may setup retail shop of homeopathy medicines.
-You may work in industries dealing with homeopathic preparations.
-You may start your own pharmacy.
-You may work in public and private sector.
-You may work in private or government hospitals, clinics, NGOs, etc.

If you have someone abroad things can get much easier. Experience matters a lot for the same. You can apply in all the international job sites.
