Commerce

Hello Gautam,
Software engineering is a branch of engineering. You need to have science background to pursue the same. As you have enrolled in commerce, you cannot opt for computer science engineering. However, if you want to proceed further with computers, mathematics and computers as your subjects in your class 12th, then certain universities allow such students for BCA.
I hope it helps.

After completing B.Com, you have to try some courses in education like B.Ed or Diploma in education I.e. D.Ed. However several states take an entrance test for the post of assistant teachers where minimum qualification is 10+2 and like TET in Bihar.

Yes, you can pursue B.Com after class 12th.

No, Only PCM students can go for BE.
