B.Com

You should complete your Diploma, you will eligible for both the courses.

You can pursue courses like CA, CS, and ICWA along with your B.Com.

You should opt for B.Com.

If you are interested to get a job in different companies then try to pursue following courses along with B.Com as
(a) ADCA in finance and accounts from recognised training institutes.
(b) CAT i.e. certificate in account technitian from ICWAI or ICMAI.
If not then you can start your preparation for Bank PO, SSC etc. to get jobs in government sector.
(c) If you want to continue your study, then you may pursue different courses like M.Com, MBA, CA orCMA (ICWAI).

You can go for either AICTE or UGC affiliated universities.

As there are many institutions that provide good knowledge in finance, so it becomes difficult to answer that which institute is good or let's say the best.
As IIBF is the institution that is named after India, I would prefer you to do some research over it and then take your final decision.
Best of luck for your future.

Hello,
It depends on your study schedule, if you have taken commerce in 11th and 12th then you will not be having any problem in scoring good in B.Com because you may get financial accounting and other subjects in this course. I would suggest you to concentrate more on accounting subjects and make a schedule for yourself about how to study.
All the best.

Hi,
There are no good jobs available after B.Com. so, further studies is suggested after the same.

Dear,
You have to join any institute for English communication course like British council.
They have programmes for basic learner that will help you to catch the English medium and according to me, you should go for advance level in the same for your future growth.
All the best.
