B.Com

Hello Sanketh,
The bitter truth of any B-School is that they are management colleges which improve your managerial skills. When it comes to Ramaiah, you can get a gist of what is expected from a manager. It depends on how you mould your oppurtunity. I suggest you to go beyond to IIMs but with 7.25, Ramaiah can be a wise option if you are looking for placements. But there are a lot more options if your expected outcome is proper knowledge.
All the best.

Of course, you can. It depends on your interest.

Hi,
It will take 4 years.

Yes, if your age is less than 21.

Some colleges do. Especially in Calcutta, but depends on the university and your marks should be good.

Yes, you can. You may have to still study maths in B.Com but you'll get through.

Now Diploma is an obsolete course in hotel management. You may plan for Bachelor's degree in HM or Diploma in aviation and tourism can be done, if not interested to apply for one more graduation.
