Kevin was my instructor for the last two classes and I thought he was phenomenal. I quickly started to like him and hope that he can become an instructor for more of these courses. He went over homework and practice tests which allowed questions that we could not answer ourselves to be explained and thus we wouldn't miss them again. He also had extremely helpful walkthroughs on reading and science which in my opinion are much more helpful than just telling students a bunch of tips because with the walkthroughs you can see precisely how everything is done and you don't need to memorize some strategy you might not use. He also was more than willing to extend the time of lesson over its three hour limit, which is how it should be because the goal should be to teach the students as much as possible and not say we'll leave it for next time or try to get out a few minutes early. Overall I like that Kevin had a great character and truly cared about teaching rather than seeing the class as a job that he simply had to go through. I think this course is good as it's set up but I think by far the most vital part of the course is the instructor because I don't need an instructor to read the ebooks I read myself from the course, I need an instructor who actively tries to show how to tackle the problems and focuses on important points rather than wasting time on the same points we've repeated every week. I think Kevin showcased all of this and he deserves to pat himself on the back for that. I would just recommend to him to slow down a little on more complex subjects; I personally had no problem with his speed, but I could see how some people might get a little lost. My main point is that I think the most critical part of this class is the instructor and prepexpert must insure that they get instructors who are enthusiastic about teaching and expand beyond the slides when they are teaching. Great job Kevin and I think due to this course I will improve my score.
