I took a 6-week class with David Ingber and it is amazing how in such a short time you can learn so many valuable techniques to take the test. I hadn’t been to a classroom, as a student, in about 8 years so I went to my first class kind of nervous; it did not last much since David’s teaching methodology makes you feel confident and keeps you motivated. His classes are not only fun but also very productive; they are very dynamic, interactive and different all the time. David is truly a great instructor! I highly recommend the course with David to people who are starting the gmat adventure and for people who already went through it and want to improve their score.
