“I took the 6 week capstone SAT course with Miguel Chavira and Calvin Zhang, I really enjoyed the course because I learned 100 strategies in these 6 weeks with my instructors which not only helped improve my score but also enhanced my test taking abilites in school. My instructors were also really helpful, not only did they just teach me, but also guided us through every strategy and homework material in detail and made sure we always left class with no questions in mind.”

“To be honest, I expected long, boring lessons with endless practice tests that I would dread. From the first class, that opinion changed. The energy and support from my instructors, Miguel and Calvin, made a huge difference. They cared about helping us understand why certain answers were right and what to look for in the wrong answers. Not just formulas and rules, but WHY. This course has taught me how to think like the SAT. I learned strategies and skills that improved my score by over 200 points! By the end of the course, I was excited to take the practice tests to see how much I could improve in just a week. At the end of the course, Miguel said, "You guys did this. I just gave you the materials." This was encouraging, but without his clear strategies, patient explanations, and constant reminders that we COULD do this, I know I wouldn't feel as confident heading into this exam. I am so grateful for the tools, structure, and preparation that I gained through this course. I will not only take this into my exam, but into the rest of my academic career.”

“Overall I think that this class helped me a lot in improving my score and I liked how my teacher for the course, Miguel Chavira + Calvin, not only went over all of the tips and strategies that are in the slides but also add some of their own tips to it as well. I think that this course is setup in a very good structure and it helped me have a solid study plan every single week and the repetitiveness helped me get all of the skills down and it really made the test not seem so daunting.”

“I loved this class, one being the resources they provided. It helped me a lot with what I was struggling with and especially the way that Mr. Chavira was teaching it. The amount of practice that I got because of this class was phenomenal. It overall increased my score by 200 which is a very good amount. I would say this class is a hundred percent worth it.”

“My instructor was Miguel Chavira. Helped me better understand the test and how to take it. Also helped me freshen up on some forgotten math and reading equations. Would recommend this guy to anyone I know. Hope he does well in everything in the future.”

“I had the opportunity to learn from both Miguel and Calvin during my SAT prep, and I’m genuinely grateful for the experience. Calvin provided solid support and kept our sessions organized, but I especially want to recognize Miguel for the incredible effort he put into helping us truly understand the material. Miguel consistently went above and beyond—breaking down difficult concepts, checking in with us individually, and making sure no one fell behind. He explained strategies in a way that made everything click, and his dedication had a huge impact on my confidence going into the test. You could tell he genuinely cared about our success. Thanks to both teachers, but especially Miguel, I walked away feeling more prepared, more capable, and motivated to push myself further. I can't thank him enough!”

“My instructor Taylor Trautwein was below par. During the math section, she got some answers incorrect, and during the reading section, she did not explain each answer choice—she immediately jumped to the correct one. She even explicitly said in class that she didn’t know something and was just going off the answer key. I feel that if she does not fully understand a concept, it becomes difficult for her to effectively explain it to us. On another note, the weekend review as a class was helpful. It was good to understand and get an overview of all the strategies as a quick reminder. The only downside was the instructor. That said, I thought the overall class structure and material were strong. My favorite reading strategy was BOSS (Build Your Own Simple Solution); it helped me focus and simplify difficult questions. For math, I really liked the TAC (Try Answer Choices) strategy—it made solving challenging problems much easier. I also appreciated that we were given tough math, reading, and writing questions instead of just hard math quizzes. The tougher content helped push me and exposed areas I needed to work on. I think it would be even better if there were more time built in to go over homework. Being able to ask specific questions helps me learn more effectively. Overall, the class was valuable, and with a more knowledgeable instructor, it could be great.”

“Before Prep Expert, the SAT and I were in a toxic relationship. Enter Ilia Kolmagorov: part tutor, part wizard, full legend. He made math make sense, turned reading into a game, and somehow made studying... fun? My score shot up faster than my caffeine intake during finals week. 10/10 would panic less and prep with Ilia again.”

“My instructor was Ilia and I really enjoyed his course. He tried to make it fun even though it was studying on the weekends, he added jokes to try and make it more enjoyable, and made it sound like he cared for us on a deeper level. I started out at a 1100, but in practice tests i have been getting in the 1400s. He made everything more enjoyable even when I would not want to go to the classes due to it being on the weekends. I truly feel like i got better and have a much better understanding on the material that is shown on the test. I’m very grateful for him and the course.”
