well since your replying slowly and i have to go out with some friends so here's a general outline for some easy high scoring subjects

indo-pak history --scoring enough if studied well + helps in compulsary GK papers

psychology-- easy to study (many of my elder friends with no previous background did very well in it)

sociology,journalism,muslim law --any two you find easy..generally all 3 are quite easy and good scoring..the rest depends on you and your interests
