Hello,

BSc in maths will be more better , having good scope , if you did BEd as additional degree , can be teacher at good reputed schools or Colleges. Then can have good future career.

Also, it depends on what you want to study. From my knowledge, you want a B.A. if you are planning to apply your math skills to a social science, like economics, and you want a B.S. if you plan to go in a field that uses straight math equations and hard math.

I hope that helps you to make a wiser decision. Rest, the success in any field depends upon your own quest to knowledge, hard work & networking skills.

All the best.
