Salam! I am new here and this is my first ever post at this super-helpful form.
About myself, I am an overseas citizen, currently pursuing my masters degree.
I finally decided to appear for the 2018 exams (out of nowhere really) but I am pretty determined on getting it right the first time (over-ambitious, I am aware).

I am trying to finalise my optionals but would request suggestions and opinions on the matter. So here goes:

- Computer Science (doing MS Computer Engineering)
- International Law (no idea about this, but read it's doable?)
- US History (have some foundation to build upon)
- Environmental Science (again, possess some informal education but nothing concrete really)
- Psychology (super interested in this, but no formal training)

My question is: What are your opinions on, say, the average time and effort requirement for each of these in order to do the syllabus justice. Would you recommend any other options?

Looking forward to your kind responses. Thank you!
