Believe me its not as easy as one may think... Things look quite simple when looked from a distance... Solving a CSS paper in examination hall is a real test of nerves and patience... one may even forget answers of easy questions at that time... Objective was not much easy... It was average... Some questions may even not be answerd at first sight by those having done Masters in Islamiat like no. of rukus in surah hajj, which sahabi died in the hands of holy prophet(PBUH) etc.
Also, easy papers are difficult to be dealt with especially when large no of candidates are appearing in the exam. It really becomes difficult to create difference, consequently score turns out to be low.
