This course covers everything- and I mean everything! It was a beneficial SAT prep course that covered vocabulary, reading comprehension, grammar, and also math concepts! It left no stone unturned. What stood out to me were the expert strategies that went beyond the basics. I felt like I was getting insider secrets from College Board itself! SAT instructors Isabella and Ethan were very helpful and have definitely helped me improve my SAT score on my practice tests by 200 points! I seriously think this is a great system that covers BOTH the basics and the hard strategies. Prep Experts is also extremely cooperative and offers office hours as well for students to drop in and ask questions, which I think is useful and helpful. As for the course itself, it had basically identical questions to the actual SAT. I thought that I would have a hard time focusing since it was a virtual class; however, that was not a problem as the classes were engaging and insightful. If you want a course that is worth your time, take this one!
