Can I pursue CS along with my regular degree?

Dear Udit, Yes, one can pursue regular college alongside professional course but before to that, check for permission from the ICSI. Secondly, my recommendation is to go for regular college only if you are getting admission among one of the best colleges. Else, opt for correspondence graduation and

Yes, you can go for it. It adds value to your current course also.

Yes, CS can be pursued after 12th and you can do it along with a degree as well.
