Hi!
I red your comments and suggestions for GMAT prep.I have few questions for you. I aim for top MBA schools. I have a medical background.No math. I took the GMAT and scored 470...I need to get back and get an above 620 score! I work a lot and have a family. I realized that the biggest problem for me is math, and more specific percents, combinatorics, geometry, probabilities. I am looking for help in math but the private lessons are incredibly expensive! You mentioned the Delta course....could youdevelop a little? Is it a good math preparation? Any other suggestions for math? Your answer would be greatly appreciated.
