Dear Aspirant,

If you are a good student at mathematics and want to make a career in the top computer science fields like full stack development or data scientist then you should choose btech. Also if you want to pursue engineering in any other field like electrical or mechanical or communication then btech is the option.

However, if you just want to study the computer subject not in depth and want to make a career in the simple IT field and not very good academically at the mathematics, then BCA is a good option.

But if you are interested in genuine mathematics and a good student then go for btech.

Hope this helps. Thank you.
