BCA

Hi,
IGNOU is one of the oldest and recognised. You can also check out Annamalai, Karnataka State Open University, YCMOU etc but before doing so email some universities abroad to check if they will accept correspondence degree. Many universities do but you will also come across universities which will prefer a full-time degree.

Dear,
As BCA is a 3 years degree course - after completion of your +2 in commerce with mathematics, you can pursue BCA following the marks and other eligibility criteria of the institute, you intend to get admission. Best wishes.

Both of these courses have their own advantages. While students who are interested in the field of internet or database operations can opt for B.Sc IT, those who want to pursue a career in computer applications, programming and software should go for a BCA.

Hi Akhil,
You will get many options abroad, Canada, Germany, Singapore, Ireland, Netherlands, etc. You can look for network engineering courses if you are interested in this field. You may look for PG Diploma in the same. If interested in research you can think about obtaining a Master's degree in future.

If you want to study abroad, you can opt for Master of Computer Science in the US or go for M.Sc in IT in India.

College change or university change after first year is completely dependent on college and university norms, some university allow it and some won't plus you need to have good scores in first year to apply for the same. For further details contact the college authorities.

Please elaborate your question for better assistance, what exactly do you mean by open admission?
