Hey Ashok !

Your +2 level percentage seems to quite good to help you secure a seat in a number of career fields.

Since you are a Bio Science student, I guess Engg. won't be favourably your choice.

Thus, leaving you with 2 broad options : Medical Field and Research Field.

If you opt to be a doctor, no doubt you would be gaining quite a respect in the society added to that is the salary which also would be good. Greater the number of degrees one has in Medical Field, greater are the chances of being recruited by Famed Hospitals. Starting off with MBBS, go for MD/MS then superspecialization.

If you want to go for Research Field, you need to do a B.Sc. in a subject of your choice, some of the top Institutes being IISc, IISER, NISER. Then go for M.Sc. and PhD. Your career would be too good from knowledge as well as salary oriented.



Hope this helps.



Good Luck !
