As I checked in ur profile u r India am bro me also learning coding when I was in class 8 now am in 11 ☺️ n An Navodayan 😉 so about ur questions u should choose math's stream in class 11 n start preparing for IIT JEE and then if u will crack it then ur life will totally turn in new direction anothwise if u wouldn't crack it then it's ok no rush ☺️ just give 1 year time for urself and keep learning by urself believe me if u will just give 1 year with full dedication on that u can attain more than an initian by the way first try for that n then that is another case but for sure now u should leave everything and just prepare fir it evn stop coding and start learning pcm 🙃and after that when u will in iit then ur coding will be 😳😳 I hope u got it ☺️
If you love maths and you like to solve problems then go with science-maths + cs -> then do Btech
If you are good at remebering thing(ratta in hindi) then go for science-bio +cs and then do BCA.
or commerce+cs -> BCA
(If you are interested in computer then go for bca after bio or commerce else you can go towards medical or commerce field)
