B.Com

Yes, you can but it is better to do MBA for your good career with B.Com degree because it would be difficult for you to start career in IT with commerce background. Maximum MNCs want B.Sc IT/CS, B.Tech or equivalent.

No, it is impossible to complete both B.Com and MBA within 3 years under Indian education system. You have to complete 3 years of graduation and then you have to go for 2-year MBA.

It is better if you gain some experience then you can go longer in SAP.

I really don't know about this as I scored good marks. But still you can try.

CA, law practice and finance manager are very high paying jobs after B.Com with additional qualifications.

Getting admitted at this percentile is difficult.

Your scores are really good, you can get admission in any of the top B-Schools. Asia Pacific institute of management is one of the top management college in Delhi NCR region. You can apply for the GD PI by filling the online form through their website - http://www.asiapacific.edu

If you are good in studies and interested in commerce then do B.Com and if you are not or if you like hotel management then go for it. Moreover, B.Com is a universal degree, i.e. you can do whatever you want to do after B.Com. On the other hand, HM is the type of degree based on your creativity and skills and less based on studies and after proceeding in this field you will not have any option to change your field.
