I had spent more than ten hours on the syllabus of all optionals.
My optionals are included with;
1: International Relations 200
2: Us histroy 100
3: Gender Studies 100
4: International Law 100
5: Punjabi 100
As far as Us-Histroy is concerned, Firstly it's vast ( No doubt) but it can help in International Relations and Current affaires. Secondly more than 70% syllabus is very easy to prepare and interested as well.
Thirdly it's scoring. A CSP has fetch 89 marks in 28 days preparation
I am definately going towards US histroy..
Who wants to take risk of Town Planning as a new subject?
