Hello Aspirant.

Hope you are doing good.

Yes, for sure you can take geography course or study geography as a subject in college the college even if you don't have geography in your class 12th. There is not need to worry about the if you don't have studied or take geography in class 12th due to some reason reason so you'll not get admission in college in geography course or you cannot study geography in college nothing like this will going to be happen. You can take geography subject or course in the college.

But I'll like to tell that every institution has different rules and regulations for giving admission to the students in the courses so may be some institutions will demand geography subject in class 12th as a compulsion to take geography in college but no need to worry try in some other institutions.

GOOD LUCK, STAY MOTIVATED AND HOPE THIS HELPS.

Thankyou.
