Hello Aspirant, Hope your doing  great. As per your query , for your rank that is 230 so you can get in BITS PILANI  as a branch of MSc Mathematics, in BITS Goa you can get MSc Economics and in BITS Hyderabad youcan get seat in a branch of Msc  Economics.

With a score of 230 in BITSAT, it's unlikely to secure admission into any B.E. (Bachelor of Engineering) programs at any of the three BITS campuses (Pilani, Hyderabad, and Goa). This is because the cutoffs for these programs are generally much higher, often exceeding 300.

Integrated M.Sc. Programs (Only BITS Pilani Hyderabad):

BITS Pilani Hyderabad might offer admission into some of its Integrated M.Sc. programs with a score of 230, depending on the competition level that year. These programs combine a B.Sc. degree with an M.Sc. degree in a specialized field. However, the cutoffs for these programs can also vary.

B.Pharm (Bachelor of Pharmacy):

You might have a better chance of securing admission into the B.Pharm program at either BITS Pilani or BITS Hyderabad campuses. The cutoffs for B.Pharm are generally lower compared to B.E. programs.
