Mark Sullivan helped me increase my score by 90 points!

After taking a GMAT prep course and studying for two months without seeing my score improve, I decided private tutoring may be a good option for me. I did a lot of research and found Mark had great reviews so I reached out with one month left until my test date. All I can say is THANK GOODNESS I did! Mark helped me pick apart my strengths and weaknesses. He showed me exactly what to focus on to increase my score. Not only that, he also taught me tips and tricks on how to best take the test. Mark is patient and always happy to help, and he knows this test inside out. If you REALLY stick to the homework he assigns (redo log especially), you will see an improvement. Every penny was worth it. THANK YOU MARK!
