hi,

see agriculture science and physiotherapy both of the course has decent career options and you may get job in government sectors as well as private sectors. however if you want to settle for corporate world and business domain it would be better to choose agriculture science over physiotherapy, after completing b.sc in agriculture science you may apply for mba course in agri management which has excellent job options like relationship manager, finance head, sales manager, quality controller etc. however based on your score you have fair chances for below mention institute:

BPS Agriculture, Purnea

COA Agri, Dumrao

TIRHUT COLLEGE OF AGRICULTURE

hope it would help.
