I'm currently a junior. When I took geometry and algebra 2, it was really hard for me. I think it was because I never got enough time to soak in the material we learned, because it was so fast, we learned a new lesson everyday. I have a year from now until i get out of high school. What can I think to improve my math skills? Summer is starting soon, so I'll have a lot of time to study. any books, or anything I can get?
