B.Sc

Hello,
As you are choosing Maths, then you have to take 3 more subject in which English is compulsory. But, it differs from college to college. You have two options for choosing the third subject, it is either Physics or Chemistry. 4th subject depends upon your choice and college subject list.

Besides Engineering, there are new generation streams and offspring such as Information Technology, Avionics, Petroleum Engineering, Nano Technology, Aeronautical Engineering, Mechatronics, Automobile Engineering, and Robotics and so on. Considering the trends in growth of industry, electronics and computer sciences streams are predicted to have good prospects in future. But a B.Sc in Maths or Sciences, Bio Technology or Bio Informatics, BBA BCA are also found to be preferred by many including those who fail to clear entrance examinations.

Yes, you can pursue B.Sc Agriculture but you should have completed class 12th with science stream. There is an ICAR (Indian Council of Agri Research) scholarship programme for toppers admitted to the degree.

She can do it once she finishes her B.Sc. Whichever college she wants to join all she needed is above 50% in graduation as the graduate degree will be provided to her later, so the college will ask for the last year's mark sheet and the course completion certificate of UG degree that would be enough.
