Assalam O Alaikum,
I have done M.Sc Microbiology. My optional are Zoology, Psychology, Journalism and I am confused between Int. Law and forestry. Please tell me which one of them would be a wise selection and please rate my combination.
And please also tell me you cleared your CSS exam in first attempt or in 2 or 3 attempts? I mean, is it totally impossible to become a CSP in one attempt or just hard?
