I think the prep expert courses aren’t entirely worth the price and work of the classes because the curriculum is concentrated into a single PowerPoint presentation, which can be read in a short article by anyone without the need of an instructor. The teacher Tessa Gebert was very helpful, but I believe they could have been more familiar with the course and updated on recent important changes to the SAT test that could affect students’ scores. Compared to PSAT scores, I have improved, but most of my improvement was from practicing the tests instead of learning from the courses. The courses do explain a lot of strategies on how to make the test easier or faster, but most of the teaching time is wasted on reviewing many basic mathematical concepts or mechanical functions in English. If the course was written into a book, then it would be no longer than 50 pages. I believe most of the improvement on SAT takers can be made through completing questions and quickly reviewing the key concepts. The course was not a waste of time, but there were days when easy course material was reviewed for too long.
