I thought Prep Expert was helpful in some aspects. My instructor was Ilia Kolmagorov, and I believe he did a great job in keeping the class engaged with his humor. The tips and tricks were useful, but I wish we had more time to answer some practice questions by ourselves during class, instead of mindlessly going over practice questions from the homework. More polls throughout the class would be more helpful in my opinion, because it allows students to critically think about more questions right after learning about the tips and tricks. Overall, I have seen some progress in my test scores, and I thank the Prep Expert for my improvement.
