Should I choose MCA or engineering carrier after 12th?

Answer 1

Should you choose an engineering career? (I'm afraid I don't know what MCA is in this context.)

Engineering is a very rigorous course of study in college, arguably the hardest four-year program of any major. The upside is that engineers are highly sought after graduation and you will likely earn a good salary. After several years of work, you qualify to take the professional engineering license test, which can put you another step higher if you pass it.

If you can handle the tough course work, studying to be an engineer is an excellent thing.
