I am currently in my second year doing BBA in Karachi. I want to attempt the CSS exam in future. I have a good amount of time as of now. I have gone through the syllabus and listed down the optionals that I fill are good for me. Now, I just want to get the suggestions that are these subjects somehow related to each other or does these have intersecting topics?

1. International Relations
2. Public policy and governance or Public Administration
3. International Law
4. European History or Indo Pak history (I have a good grip on both subjects)
5. Gender Studies

I am already working on my compulsory subjects and study optionals in free time. Keep in mind that I'm in my second year and have two more years. I'm reading few books and watching youtube video for studying European History and for gender studies I have a good base in philosophy and idea related subjects. Help me out. JazakAllah

You should definitely choose Accountancy and Auditing and Business Administration as optional objects. If you prepare well and Exam, you could potentially score 150-175 depending on the difficulty of the exam. IR and Political Science don't offer you that score. Since you are doing BBA, I high encourage you to take AA and BA.

I think taking business administration would be ideal but I am not that good in accounting so I thats why I personally feel that taking IR would be better. Plus I'm going to take management as my major and it will have IR as a course.
