Hello Dhiraj,
You have not mentioned anything about yourself. Why break after graduation? Normally for M Sc you would need to have done B.Sc. I suggest have a look at the different courses offered by IGNOU. I think this is best solution for you.

Dear,
If you mean MPC as +2 board with physics, Chemistry and Mathematics combination, I will say, that it is a better option. After +2 with PCM, appear in JEE mains or state joint and go for B.Tech in your preferred field.

Hello Rajat,
I appreciate your interest in pursuing Bachelor of Technology (B.Tech) or Bachelor of Computer Application (BCA). For B.Tech, IITs and NITs would be the best option. For BCA, Christ University, Bangalore or Symbiosis University, Pune would be the best options. Choose as per your interest
