Bachelors

Actually, mathematics is the subject which is common for any domain [exceptions can be taken for one or two fields] that is to be done by a student in the first year of under graduation. Your main course will be from second year of UG such that even though you choose any field there will be a subject called mathematics in first year. Any how you have done your intermediate in IT domain as well as Bio domain, it is better to opt B.Tech because you have Computer science, Information Technology and Bio-technology branches in engineering. Based on your interest you can choose one of them and proceed forward.
I hope you will take a wise decision! All the best.
