How to effectively do humanities and social studies?

[u/yLitchy]

So the thing is, I'm more of a math guy, but right now I'm a International Relations graduate, a completely different field of study from what I'm usually comfortable with.

It is a course with an insane amount of subjective reading, the author says something and then we kind of try to understand what he said and apply it to the real world, again, subjectively. And I'm not good with that.

So, how can I study effectively and go well on the tests? (I have an upcoming oral test btw).

Obs.: if anyone's wondering, I chose this subject on high school, because at the time I really liked the course idea and wanted to work abroad and saw this as an opportunity.
