Hello ridhima.arora

I hope you are doing good. I would glad to inform you that you must pre-decide your path at the time of choosing subjects. Atleasr you should that you want to go for btech or mbbs because entrances based on these courses are jee main and neet and their prepartion usually start from 11th only . So it would be difficult for you to preparation because level of study , paper level is different . Taking pcmb is good option in a way such that you are not getting any good medical colleges and then you take btech as options if you have developed your interest and it can be also beneficial in calucalting the best 4 percentage.

Hope you found this answer helpful. Good luck for your future

hi,

see you did not mention which of the exam you are asking for, however if you are confused to take 10+2 subjects, then let me explain that taking physics, chemistry and mathematics is compulsory in most of the schools or institute. however students may take forth subject from biology/ biotechnology/ computer science/ statistics etc. so in case you are interested to study about biology related stream in future you may take biology as forth subject.

however in case you are interested to make career in engineering domain , then it would be best to select statistics/ computer science as forth subject.
