B.Com

No, you don't have to. You can go for hotel management after completing class 12th.

It is a great choice. You have good scope with work experience. It will be useful for your further studies in abroad or India.

You are eligible to join as TGT in any school based on you B.Com, B.Ed educational qualifications. You can now seek job or study M.Com. M.Com will make you eligible for PGT jobs and growth in the field of education administration.

B.Com have less mathematics. It depends on you that you want to go for mathematics or not. You have to do some basic calculations in accounts subject. In BBA, you have only one year compulsory mathematics subject.

Both, BBA and B.Com are undergraduate courses. BBA is a professional course, whereas B.Com is an undergraduate commerce course. If you are planning for MBA, then you can go for BBA as it will help you more than B.Com. If you are planning for M.Com, then you can choose B.Com as you can't go for M.Com after BBA.

Hi,
Apart from regular courses, you may pursue either of the following programmes if required:
(a) CAT (ICAI/ICMAI) i.e. certificate in accounting technitian+ADCA i.e Advance Diploma in computer application from recognised training institutes.
(b) SAP modules in finance and accounting.
(c) SAS in finance and accounting. Selection of courses depends on the kind of jobs and company. For more details, kindly visit the respective websites and https://shiksha.com/courses/SAP or SAS.

I will like to recommend BBA over B.Com because it will offer your wider scope and opportunities and also you will be saved from your little uncomfort level with maths.

It depends on the preparation of your exam. If you feel that you are ready to give exam then go for it. But, if you are not prepared then go for it after completing your B.com.
