I had a great time learning from Prep Expert! I went into the course knowing very little about the ACT, causing me to struggle a little at the beginning. As the course went on, I gained confidence and the skills to take the test efficiently. If I were to have any complaints it would be that the course gets repetitive and the math review is a little spotty with them not covering complex enough topics while driving easy ones into the ground. My instructor Will York was very good at giving in-depth explanations, which were especially helpful in difficult math problems
