I have a Set Theory test in 15 minutes Veeky Forums. What is essential to know?

i can do these two proofs, never taken a class in '''set theory'''', physics major. Barely done any maths modules. Is maths a fucking meme subject?

>Is maths a fucking meme subject?
Not if you go to a non-meme uni/country.

We also have a set theory course, but these questions are settled in the first semester and have absolutely nothing to do with our "set theory" course which is more advanced math.
