Hello aspirant

As per your question, all total 16 IITs across the country offers BSC mathematics.

All u want to do is that u have to crack the JEE mains exam. That's it.

Hope this information is relevant to your question.

If you have any enquiries please feel free to ask.

Thank you:)

Hello Jaya,
Yes , all the IITs offers B.Sc in mathematics but for that you have to qualify JEE.
Good Luck!!
