Hello,

I hope you are doing fine,  To me anything you choose and your interest subject is good. You are the only one know your heart.  If you are interested in computer applications and you wanted to do MBA in future so BCA is best option for you, and if you are interested in engineering then no doubt polytechnic is the best option … mainly students doing polytechnic after 10th but you are asking after 12th.

I hope you find this information helpful. I wish you all the best for your future.

Good Luck
