Funny, I got a Chemistry + Biology + Physics "blank" exam next Friday (I'm studying medicine). Pretty stressed about it, I have to know everything by heart and haven't done anything apart of electricity yet.
The cool thing is that chirality and functional groups are things I've already learned in middle school, 'cause colleges' programs haven't changed since the 90s while schools' one did.
The uncool thing is when teachers assume you already know something you never saw.

don't worry, chemistry is a bit like programmation when you thing about it. Atoms are like tiny functions that do something particular when they come across other atoms (you "pass them" to other functions).
So molecules are like high-level functions, combinations of functions, as if you were programming in a functional language.
