I'm a beginner, need attention and than suggestion of seniors regarding subject selection. Bit confused in IR vs Political Science. My seniors (some of them are CSPs) they suggest me to go with Political Science and the fact is that at their times/attempt (2015-16) they choose IR and qualified but now they're suggesting me Political Science, trends or other factor?

My optional:

Political Science
Constitutional Law
Gender Studies
Governance and Public Policy
and last one is Sociology.

No background of any subject, and i go through IR outline and past papers as well Political Science. IR one is bit easy (past papers as well outline) but day to day changing scenario and current subject, and on the other hand Political Science is limited at some sort and predicable (no such variation in marks, trends) and importantly its in minority(limited ppl opt) subject (majority ppl opt IR). kindly share your experiences, suggestions, JazakaAllah.
