B.Sc

Yes, you can go for B.Sc. IT after your 12th with commerce as eligibility criteria for pursuing B.Sc IT in most of the top universities is pass with 50% marks in 12th class and you might have to qualify some entrance test. It will be advisable if you do your degree from a well known university and that provides prime placement opportunity, outstanding exposure and professional enhancement training. I am enlisting some of the top universities for your help:
Symbiosis University, Lovely Professional University, Institute of Law, Kurukshetra University - Kurukshetra
K. L. E. Society's Law College
LJ Institute of Law-Ahmedabad
MS Ramaiah College of Law - Bangalore
Modi Law College-Laxmangarh, Rajasthan.

I would prefer a B.Tech over a B.Sc. Owing to the following reasons:
I) B.Tech will give you a technical hand which is highly preferred by companies. A technical person is supposed to tackle problems with ease. Ii)B.Tech will give you more salary in any firm or company. B.Sc. Person will get comparatively lower salary. Iii) The syllabus of B.Sc. Is vast and it is far more then B.Tech syllabus. So if you are a decent student, you will do great in engineering. Iv) You have more career options available after B.Tech. The options after B.Sc. Are limited. V) You have an opportunity of foreign placements through B.Tech while simple B.Sc. Will not get you a foreign call.
