BCA

Hi Vipin,
Ideally, it should be recognised but you must check with the universities directly. Degrees approved by UGC-DEC are accepted globally but every university has its own admission requirement. Some universities will allow you to apply while some may require a qualification assessment of your degree to check its Canadian equivalency. You may email the universities and they will guide you as per their norms. Nothing to worry here.
Good Luck.

BCA + MCA open almost all the doors for most of the IT job profiles and companies. Don't focus on which company you will get through, just focus on the technical knowledge and enhance your practical skills. Bangalore being the IT hub of India, you will never be short of job opportunities.

It's a good university with decent placement but to know the exact scenario for faculty and placements, get in touch with the current students through social media or in person.

Can you please let me know which all subjects you had in commerce? Anyways, I would suggest you to opt for B.Com.

Graphic Era Unversity is the best college for the same.

Yes, you can go for MBA in IT which will help you in having the knowledge of both computers and management field. Banks generally look forward for such candidates.

It is just an average college. There are better colleges than Garden City to pursue BCA.

I would say that each year is important as you need to maintain a good percentage throughout from technical point of view. Each and every subject enhance your technical knowledge and skills which will be very beneficial while job interview too.
