Optional Subject Suggestion
 

I have Done BS(IT) and now i want to appear in CSS exam 2020 but i am confused in selecting my optional subjects. I opt
International Relation
History of USA
Public Administration
International Law
but i am confused in psychology and sociology. I seems criminology also be an interesting subject.
I have not much knowledge of the above mentioned subjects but it seems interesting.
I don't know whether this combination is good or not and which subjects should i choose?
Please someone guide me about subjects selection.
