As far as books, I recommend our LG Strategy Guide + The 5lb. Book of LSAT Practice Drills. That combo can take you from the bottom to the top!
I also really recommend checking out some free instruction. You can sign up for a free trial of our LSAT Interact self study program, and a free session 1 with one of our instructors. It's all no-obligation, and between the two you can get over 5 hours of free prep!
Hope to see you in a class!
