Hello aspirant.firstly heartiest congratulations to you for getting such good CGPA in your 10th boards.

Passing Class 10 is the time when you have to take some decisions on your own for your further studies in future. Keep in Mind that getting high CGPA doesnt mean you belong to maths  or Biology streams . It only depends on your interests.

So if you have interest in biology field then you should opt for PCB subject for your further studies or else if you want to be an engineer go for PCM stream.It depends on your  area of interest.

Hope this helps you.

Good luck for your future.
