Yes bro, you can do B.Ed now. Since you have a UG degree in B.Com and are doing PG in Kannada, you are eligible. Just make sure your university accepts these subjects for B.Ed admission. Many colleges allow it if you studied any two school subjects.

Hey Yogita:)

Thanks for reaching out!

Yes,you can do a B.Ed course with a B.com degree and while studying M.A. in Kannada. The basic eligibility for B.Ed is a bachelor's degree with 50%-55%.Since you meet this requirement, you're eligible.If you're doing your M.A in regular mode,you can pursue B.Ed in distance mode or vice versa.Some Universities may also allow Kannada as a teaching subject based on your post graduation.

Just make sure to check the specific college or state rules for entrance test or subject combinations.
