B.Com

It is totally dependent on you. But, if you cannot clear the CAT examination, then B.Com from good institute will help you to generate its job opportunities but doing B.Com from the college where attendance does not matter can't help to generate job opportunities for you.

Yes, engineering (B.Tech) + MBA is very good combination for having good scope in terms of job opportunities. Because the person has the knowledge of two different fields, engineering and management and BBA + MBA is of same field that is management.
