My class was taught by Daniel Lee, who made our lessons very interactive and relatable with his witty commentary and allusions to things I am interested in. Also, his energy kept me from getting bored as he drilled into my head all of the strategies I needed to know for my SAT. I could probably recite them in my sleep now. Although I didn't learn some basic math concepts in school yet, so it was a little tricky for me to learn them through the books. I would recommend asking your teacher or self-studying them. All in all, I believe this was a worthy investment of my time in which I saw improved results and gained a few friends.
