@TAIMURAK Sirjee i think u already know a lot,regarding your query There is no hard and fast rule that some subjects will give better marks then others just go through past scores of qualifiers and aspirants and you will notice up and down in all subjects. Islamic history is good option better than indopak because indopak is lengthy and generally not scoring. Us history is easier than forestry, Forstry is a dry subject hmmm take pub ad its average scoring with a brief course.And if you have studied Ir then definitely go for it why make life difficult if it can be easy ,its your opinion and the way you express your familiarity with the subject that will make you different from others and be able to score more or less.Hope this helps
