I learned more in one hour than in 3 weeks

My math teacher has repeatedly failed me both as a teacher and in test scores this year. Because exams are coming up I took my education into my own hands, as a responsible student would have done long before now, and I got on chrome during a couple hour car drive. I downloaded 3 images and learned right then and there what my teacher failed to teach me in a month. Tomorrow I will be mastering another math subject and my exam is on wednesday. I feel oddly confident, but at the same time I lack the mental capacity to fully comprehend the consequences I may face in the event that I fail. This will end well. God speed.
