Hi Kesharilal.....

UPSC is the exam which you are eligible to appear only after the completion of your Under Graduation course.

So,You can choose any stream according to your intrests,which helps you even if you are unable to crack the UPSC.

There is no particular sort of colleges & courses that you can opt in 11 & 12th taht helps you in the preparation for UPSC.

Hope this helps.....Thank U
