David Chong is the reason why Manhattan Prep was valuable for me

My GMAT preparation lasted for a full year. I took both the "Live Online" course, as well as the in-person course. I've never been very talented at taking standardized tests and I tend to get anxiety when I'm in difficult test-taking situations, so the GMAT was a continous struggle for me.

David Chong never gave up on me. David made himself available for help even after my course ended, and he also understood my weaknesses very well and helped me craft a plan to hit the 680 that I wanted.

For me, Manhattan Prep was valuable for two reasons:
1) Incredibly bright instructors who tend to be good at teaching students
2) The course syllabus curriculum

The above two points, in my opinion, are priceless and not easily substituted by Manhattan Prep's competition.

The only issue I had with Manhattan Prep was that I got the feeling that not all the instructors cared about my success at the end of the day. My online instructors, David and Mark, were the exceptions and were fantastic, passionate GMAT instructors. Thank you, David and Mark, for helping me accomplish my goal. However, with others, I remember waiting days to receive e-mail responses (and in rare cases, no response). Additionally, I remember attending a substitute in-person class taught by a guy named Matt. Matt was a fantastic instructor and even offered to send out a list of OG problems that were excellent for practicing the "smart #" strategy at the end of the class session. Why didn't my other instructor(s) offer to do that? The tips and advice varied highly among the instructors that worked with me.

Manhattan Prep is still a solid value, I am only voicing a few frustrations.
