My instructor was Miguel Chavira. He was very nice and made sure to answer everyone's questions. He did very well using our time for each meeting and even put together a very helpful and useful review to finish the course, which I will be using often. We covered all topics and materials in all subjects down to timing and accurately solving each problem. The course snowballed very quickly in work to-do. Time-management was really important in the course and without it there did not seem a way to catch up. Logging into meetings was simple and easy and the help contacts were quick and very supportive. The practice tests and homeworks were very accurate. All the material provided is so useful in answering every single problem. I wish there was more in depth explanation behind each problem. Some questions we reviewed were skimmed thorugh quickly. Overall I'd say the course was very helpful. I highly recommend Prep expert for the material provided. The textbooks and tests can be used very efficiently. I wished there was a little more engagement throughout the course and during meetings.
