B.Com

You can apply for three year law in the colleges like Faculty of law Delhi University, Faculty of law BHU, Kurukshetra University, IIT Kharagpur, etc. The minimum marks criteria is 50% in top universities.

Yes, you can do MBA in IT specialisation but it will convert your subject to Digital marketing.

To be very honest with you, it looks very difficult to get admission in a top B-school. But still you may apply to tier-2 or tier-3 MBA colleges in India.

Both the courses are equally good and have tremendous job opportunities. It entirely depends on how well you understand and handle the stream and increase your scope of growth. To decide on the course, you should analyse your strengths, career goals, interests, personality, aptitude and ability. If you decide based on these parameters you will put in your best effort and will be successful in your chosen field. Always remember, you should pursue a stream/course based on two things:
-your career goal
-the type of job you want to do
