Hello Student

At first you have  to take decision what is important for you CA foundation course or Bcom and on which course you are much interested for.  CA foundation course then you should have to appear for CA foundation course  as per schedule of the examination. On the other hand if you are interested for Bcom courses first then you have to appear for Bcom examination as per schedule first.

The qualification you achieved after any of the course appearing for examination and you have decided to appear for Bcom in the next syllablus of examination there will be no problem in the k in case of interview and job. For CA foundation course 10 + 2 qualification from any recognised university or board is  eligible for appearing  in CA foundation course. For appearing in the Bcom  course first will be the good decision.

This will help.
