Assalam-o-alaikum
kindly look at my optional subject I am confused in my optional selection
I have done MBA HRM I have decided 3 subjects
1. Indo-pak History
2. Sociology
3. Business admin
4. ???????
I am thinking to opt Psychology or Geography. which will be better ?

in institute i had a special class by a CSS topper he is a international debater
he said, "divide your marks instead to opt subjects of 200 marks try to attempt different subjects of 100 marks, as I have opted just 1 subject of 200 marks that was psychology, (he said) the reason behind that the answer sheet of paper I & paper II check by the same examiner".

so what should i do, should I make another combination of optional 100 marks subjects along with only one 200 marks subject ?
Kindly guide me & also give me your comments about my optional combination.
