Dear @Minfless~Genius. I've a master degree in Applied Physics but frankly speaking I am not opting it for two reasons. Reason number one is, as you mentioned that only main topics are mentioned in the outline but there are many subtopics and their derivations, one should have to prepare all the topics including subtopics plus their derivations one Numerical Problems as well which takes a lot of time to get well through all the syllabus. Therefore, one can easily prepare any social science subject instead, if have interest in any. Second reason is essay, social science subjects help in essay and build basic knowledge which is useful.This is purely my own opinion rest the decision is yours,if you want to know more about how much depths you need to go into a subject then you should analysis previous papers.
This will surely help you out to select the subject.
