B.Sc

No, I do not think direct entry into the 2nd year would be allowed in most institutions. Lateral entry into a different college is only permitted once you have begun your course in B.Sc and have completed your 1st year in B.Sc. You can then apply for lateral entry into a different college in your second year.

PG courses and further studies: B.Sc. graduates may go for relevant Masters course (M.Sc.) or PG Diploma course. Some such Masters courses include- M.Sc in Dialysis Technology, M.Sc in Renal Replacement Therapy and Dialysis Technology, M.Sc in Renal Science and Dialysis Technology and M.Sc in Dialysis Therapy.
M.Sc course lasts for a period of 2 years. PG Diploma course generally lasts for 1 year.

It will be better that you should take MBA marketing. You can join as market research analyst your B.Sc maths skills will be useful in this role and marketing is like anyone can join. It requires more communication skills. Background of your degree is not that important.
my suggestion is you can go for MBA Marketing.

Hi Angom,
Different universities have different entry requirements. You must take the IELTS to meet English language requirements, you have to check the minimum score requirements on university websites. If you plan to study in US you have to take the GRE.

You can either do a Masters or Post-Graduate Diploma or Post-Graduate certificate course in Canada.

Hi,
You should mention your stream. Well, as you didn't mention it, I can't give you the appropriate answer, but for better placements, you can opt for M.Sc, PG Diploma, M.Sc with training, PG Diploma with any other short-term course related to your stream.

Hi,
The best colleges for your course are:
CMC (Christian Medical College)
JIPMER
JSS University
According to me, JIPMER is the best because of ranking, less fee structure and the medical facility.
I hope you got your answer.
