Can I take admission to B.Ed Math if I do not have math as a subject in my BCom. I have math in Class 11 and 12.

Yes, even if you completed B.Com without maths but had maths as a subject in your 11th-12th class you can definitely go for B.Ed and can choose maths as your subject. Though necessity of mathematics depends on the specialisation you choose and the institute you are planning to go.
