Go for MPH. Master in Public Health nowadays is a very good course for various health related professionals. MPH after BASLP will be a good decision as you may relate to your course and will be easy for you to cope. Public Health sector has a broad scope.

Do you mean Post-Graduate studies in Business?

Well, that depends on the University and the course that you are pursuing. Different universities have different cut-offs. What you have to do is fix a course. Once that is done, check which University offers that course. The details can be obtained by Googling and the information regarding the cutoffs will be obtained in the respective websites of the universities.
All the best.

MS is much better nowadays if done from institutions like IISc, ISER or abroad. Then comes MBA and BDS. MBA after B.Tech is good for higher package careers.
