I think Prep Expert and my instructor Mr. Chavira helped me a lot, especially on my English. I’m not a native English speaker and the first time that I took PSAT I only got 390 on my English section. After taking the class, my English score rises a lot! I can now get 600 or more on my English section. It’s my pleasure to have Mr. Chavira as my instructor. He helped me solved a lot of problems and encouraged me a lot. I also love the sources that Prep Expert provides. I can always go through the questions that I got wrong and even retake the practice tests. Additionally, when I have problems with my dashboard, Prep Expert replied me so fast and try their best to help me. Thank you all for helping me out.
