I took a 6-week GRE prep course with Michal, and I am so glad that I did. By the end of the course, my score improved over 250 points, and I felt confident taking on the GRE. In addition to the prep book, Michal provided us with a math workbook he created himself that was extremely helpful. Math is definitely my area of weakness, and Michal happily worked with me until I felt comfortable with the problems. The cost of the course is a steal, not only compared to the cost of other available in-person courses, but compared to the quality of other courses -- Michal really went above and beyond to help everyone in our group, and I don't think that many other instructors (particularly those affiliated with bigger companies) would do the same. I cannot recommend this service strongly enough. Higher education is a necessity these days, and applying to graduate school is particularly daunting. Michal's services are excellent assistance in the process.
