Teacher

With B.Com, MBA, and B.Ed (Economics), you cannot directly become a TGT Maths teacher in most government schools.

But with additional Maths qualification + TET/CTET, it is possible.

Private schools and coaching centers are more flexi

ble.

Yes, Commerce students can definitely do B.Ed and become teachers too if they completed their graduation (like B.Com.) with at least 50 - 55% marks.
Now, when it comes to teaching, you will usually be eligible to teach subjects like:

Commerce or Business Studies
Accountancy
Economics (in some cases)
Maths (if you had it in 12th and graduation)
Keep in mind that you will have to pick subjects during B.Ed that align with what you studied. Also, if you plan to teach in schools like CBSE or state boards then clearing CTET or state TET with commerce-relevant subjects will make your journey smoother.
