Dear Nasir,
It is useless to ask about the scoring and non-scoring aspects of any subject.
if you have interest in GEOGRAPHY, then go ahead and start preparing, you will make this subject scoring.

(On the other side if you select some so called scoring subject but you have no interest in that very subject then definitely it will be you, who will make this subject low scoring.HAHAHAH joking don't mind)

These are the words of a person who has qualified CSS.

Also following thread will confirm this also.
