I reckon my point still stands, don't you think the combination you've mentioned would be unfair to a person who has studied say maths or physics or biology as compared to someone with a degree in computer science or economics?
I agree that subjects like Persian and European history etc are not very useful for a civil servant in Pakistan so perhaps a SAT like test is a more suitable option. After all a high score on SAT is good enough to get you into Yale, Harvard and Princeton etc so shouldn't it be a good measure for judging CSS candidates?
