Hi.
Yes, you can get admission to for B.Com but you need to select college and look for college norms.
All the best.

Hi Pujesh,
If you wish to pursue MBA after B.Com, then you must clear the entrance test I. e CAT to get admission in very good institutes like IIM.

Please wait for the further cut-offs. You will be able to get admission into south campus colleges.

Well, SD College is famous for B.Com. Last year, the cut-off was at 96%.
You may get admission easily if you have sports or any other quota.

Well, for Bachelor of arts, you can seek almost any college of the city.

Hi dear,
That's a brilliant option that you have chosen, as an Honors degree will provide you weightage. Preparation for UPSC should be started once the 2nd year exams are over.
One year regular classes and thereafter revision for 3 months would be enough, if proper timetables are followed. Write back for further queries. Thanks and all the best.
