Degree

It depends on your interest. Where do you see yourself in future? If you want to run a business organisation then go for MBA. Otherwise, if you have interest in teaching field or govt. jobs then you may go for M. Tech, but as per the current scenario, MBA has a better market value.

First of all, this is not possible as you can't pursue two courses at the same time and it makes no sense to pursue Diploma and degree course together.

Hi Vaishnavi,
Please mention the name of the diploma you want to pursue, as eligibility will vary accordingly and you may not be qualified to go for each one of them.

After your B.Com, you can go for ACCA. ACCA stands for the Association of Chartered Certified Accountants a leading international accountancy body. The ACCA qualification is recognised and is treated in other countries as being equivalent to their local qualification

I hope this would suffice. All the best and god bless you.

If you are looking for good job opportunities in future then go to USA.

I have to be honest with you, I can only answer questions about my college and any courses that it may offer. I don't have a deep understanding of how this industry works, considering I'm only a 3rd semester student myself.

Dear Suvendu,
I don't know the reason why have you not been able to find a job. However, if you go for MBA, it will give you a good upgrade in your academics and a rewarding career too. I hope this would suffice.
All the best and god bless you.
