I have just passed my 10 class now I am in delima to choose my stream I am quiet good in Maths but I want to become IAS or cds so will it be good option to choose PCM or I should go for humanities?
For IAS and CDS, it is necessary to complete graduation. However according to the criteria for CDS, it is mandatory for a student to have a degree in Engineering along with physics and mathematics as mandatory subjects in Class 12th specially for Air force. Thus, it is suggested for you to take PCM in 12th as it will keep your options for all the career possibilities.

I hope this helped you.
