I hope that my history teacher sucks a nut

I just finished another test and made a 50 on it. My teacher only gives me 30 minutes to do an online test of 20 questions. The problem is who can remember all the details he asks for. There are other people making 100's (how I have no idea). Or maybe I'm just not putting in the effort. I'm not sure, but I am sure that its pissing me off. And this shit is fucking ridiculous.
