Salam!
I done MS Software Engineering and wants to appear in CE-2021 and i am confuse to select the optional subjects. As consult one of the academy and take first free class about optional subjects and then chooses the following subjects

Governance & Public Policies (100)
Gender Studies (100)
Criminology (100)
Sociology (100) or Journalism & Mass Communication (100)

and this cover 400 marks respectively but still 200 marks are awaiting to choose between Political Science or International Relation?

In my student life i am just a average student and done MS 2 to 3 years back so that's why i am not choosing computer science and its lengthy as well.

Kindly suggest me about optional subjects because i am really worried about this. And secondly tell from where to start the preparation (like compulsory or optional subjects).

It would have been better, if you had selected Computer Science.
But, if you are not opting that then I would recommend IR with US or European History in place of GPP.

Thanks for your valuable suggestion. I had checked the computer science course but its lengthy. And history subjects are also lengthy as compared to GPP. And I am thinking to select those subjects which are prepared in less time becoz I am job holder, timing is 9 to 6.

And kindly suggest me between political science and IR which is better and have maximum overlapping with other courses.
