M.Sc

Hi Farnaz,
All the online rank predictors are based on the cutoff marks provided by BITS last year. So I guess they are reliable.
However, for more clarity, you can check the last year official cutoff scores published by BITS at http://bitsadmission.com/cutoffscores2017.aspx
Best wishes.

You may opt for UK - the medical research field is very advanced, Singapore, Canada or USA.

You can but I don't feel it to be a wise decision because B.Pharma is a professional degree grasping in 4 years of your life. If you do M.Sc. then your pharma degree will hold the same place as B.Sc. Chemistry degree will hold. So it is better to go for M.Pharma and then Ph.D.
However, it's just an advice; the final call is yours.
All the best.

Here is the list of some best colleges. Please, check the list and take admission in one of them-
MS in Data Science, Columbia University.
MS in Data Science, New York University.
MS in Computational Data Science, Carnegie Mellon University.
MS in Machine Learning, Carnegie Mellon University.
MS in Analytics, Northwestern University.
Good luck.

Yes, you can apply in Maharashtra. But you will get only the seat of outsider quota which is 15-20% of total fees.

It requires B.Sc in perfusion technology as it is a specialised subject.

I wish to address the Second Segment of your question where you have said that you are unhappy with B.Com and feel you have chosen wrong path.
I wish to clarify one thing that there is no need to feel like this. Your doing B.Com has certainly benefited you. fact is that being NON PCM you could.not get into BTech. bit it's nothing wrong for you. you can Join PG Diploma in Computer Applications and energy the world of computers. PG Diploma can be done only after Graduation.
Later you take MCA through this and them may try to be expert in Computer programming or any other IT/Computer domain.

Distance education doesn't create any problem for your career till it's not completely or partially based on practical studies.
Also, distance education from a university does matter (choose wisely).
