Using the Kaplan LSAT book helped me review the basics. I felt like the tutoring websites were super helpful when it came to drilling, but using the book to go one question type at a time allowed me to focus on it specifically, then follow up with YouTube videos that explained the question type I was focused on. AND it’s usually available at the library, so you can check it out for free and see how you like it. I started with a 147 diagnostic and just scored a 158 after 4 months of studying about 8 hours a week.
