Greetings,

If you have already finished your high school or are in class 12th studying PCB then you won't be eligible to appear for JEE Mains and go for B.Tech but you can definitely go for BCA or B.Sc. in Computer applications which are also great fields.

As long as you are interested in learning programming and problem solving then you can make a career out of it. Don't let anyone hold you back on this and start learning the basics in your time to get a head start

some popular BCA exams are:

IPU CET BCA

KIITEE BCA

here are some links for more info on BCA and B.Sc. courses:
