Dear osamakhan for you psychology is much better. You can cover it easily. No doubt it contains scientific topic, though with hard working you can cover them. Apart from that Geography needs background, it is my opinion, because I have read it and made my own notes, it needs time and hard work. Withought background Geography can be tackled but needs a hord work, it will suck your blood. Hence, Psychology is very easy subject. I would suggest you go with Psychology. If you don't have interest in it, then regional languages, arabic, persian are also better choices to fetch desired score. Rest you are master of your own choice.
