MP is the best gmat service to lead into the door

Manhattan Prep comes to search when I have a tight - 3 month timeline to prep for GMAT with a full time job. I got a raffle prize for the online session so I went with David. I am good with math but bad with verbal. David was fun, interactive and clear with his sessions. He also answered my questions with emails after class when I needed. Overall I would say he's really good. Quant probs were really easy for me so I used it simply for practice tests and validate my thinking. Verbal was the challenging part. My advice for online session is that it's only a tool to lead into the door. The only way to improve the score when one's already in 700+ club is to study and reflect, know ones weakness and go fix it.
