Hello Nihal,
The general eligibility criteria for BCA course is that you must have completed your HSC (10+2) examination or equivalent (Diploma degree), with a minimum of 50% marks in total and also having mathematics as a subject in the qualifying examination.
You may also need to clear the entrance tests if required.

Score well in class 12th (PCME) board exams and JEE Mains. NDA is for defence services and merchant navy is all about trade.

Yes, you can. You may have to still study maths in B.Com but you'll get through.

Yes, hopefully. Most of the airlines ask for 160 cm. You should be able to go for it.

Hello Prasad,
No, mathematics is not vital when you have chosen genetic engineering. But then for an engineer, certain minimum level of maths should be known.

It's your career, you have to decide that what to do, no one can forcefully make you study anything. The choice is yours.
All the best.

Educational qualification depends on what kind of teacher you want to become. For teaching at the high school level, you should be a graduate with B.Ed degree and CTET and STET papers cleared. To teach at the secondary level, you should be a postgraduate and complete B.Ed.
All the best.
