SN1,SN2, E1, E2???

I never liked remembering stuff. This is why I'm forgetful.
I'd rather understand how stuff works. But I still need to refer back to the books.
So what happens when you get both of these in one subject? Organic Chemistry.

I'm too used to my other Che exams where it's all open book and open notes. Gone are the high school days where I have to remember word by word of everything in the textbook for about 5 classes. I.am.a.wizard.you.shall.not.pass. My brain's totally messed up.
