Law

Now that you have started your BBA, you can go for LLB course after BBA. Earlier, you could have opted for BBA+LLB Integrated course which would have been beneficial.
Top colleges for pursuing law are:
University, Bangalore (http://www.nls.ac.in)
UPES, Dehradun (UPES- Asia's first core sector university (http://www.upes.ac.in) - This colleges has further specialized courses in law, you can check their website.
National Law University, Jodhpur, (http://www.nlujodhpur.ac.in)
Campus Law Centre, Delhi (Campus Law Centre (Campus Law Centre (http://clc.du.ac.in/)

Generally, such long gaps are not accepted as the curriculum changes with time.

Definitely, a B.com student can do law. Besides, there are integrated courses for students interested in doing B.Com and law.
B.Com + LLB is a 5 year integrated course available in only few colleges namely:
1. Punjab University – Chandigarh.
2. Amity – Noida.
3. UPES - Dehradun
Of all these, I would suggest you to go for UPES, it is better than the other two and provides good placements as well.

Below mentioned are the National Law Universities in USA:
1. Yale.
2. Harvard.
3. Princeton.
4. Boston University.

Candidates with a minimum of 45% aggregate marks from a recognized university are eligible to seek admission in 3 years LLB course. Some universities have minimum 50% marks criterion. You are not eligible to seek admission in majority of universities based on you B.Com score.

Hi,
It is no possible to pursue 2 courses at the same time in regular mode. You can pursue one course in regular mode while the other in distance mode if you are keen to do that. However, it is perfection that is more important. It is good to do what you are best at rather than doing lot of things and ending up learning nothing. So, go for a course that you like and try to do it from a good institution offering quality placement.

You can do LLB after completing B.Com. Why you want to waste your 1 year?

To get admissions in law course, you minimum need 60% marks in your boards and a good score in CLAT. Other than PU, you should also apply to these colleges for more options and opportunities:
