The GMAT is daunting, and I didn't know where to start studying. Thankfully I stumbled upon this Manhattan Prep course and decided I might as well invest in something this important. Luckily, Mark was extremely well prepared, easygoing, and fed us exactly what we needed to know in order to ace every section. We worked through problems in class and strategies for dealing with pesky data sufficiency or critical reasoning questions that I struggled with. He showed us how to analyze our practice tests to hone in on what we should revise and time strategies. I ended up with a 750 that somehow got me into Stanford GSB, and I owe it to Mark!

Mark was great to work with throughout my GMAT studying process. Not only is he just super smart and skilled at the GMAT, but he made the material digestible to everyone in our class even though we all had varying experience and skill with the test. He also was really approachable and helpful when I had questions throughout the class and even made himself available to help afterwards. Of course, at the end of the day you have to do the work to get a good GMAT score, but it sure is a whole lot easier when you feel like you have partner guiding you throughout the process.

I signed up for this class at the beginning of 2019 after doing quite a bit of research on the course and the instructor, Mark Sullivan. Like many prospective GMAT takers, I had tried (and failed) the self-study route on multiple occasions. When I finally decided to get serious about taking the GMAT and going to business school, I knew that I needed professional guidance. What really sold me on Mark was the fact that according his Manhattan Prep bio, he was a self-confessed Seattle Mariners fan. As a Seattle native and long-suffering M's fan myself, I knew I had found my instructor.

All jokes aside, I realized shortly into the first in-person session that I had made the right choice. Mark has the unique ability to keep students engaged and excited about GMAT content throughout the 3-hour classes. It had been several years since I had been in a classroom environment; at first, the idea sitting through a session that long seemed daunting. But Mark breaks down each topic by using easy-to-digest examples and explanations, and I left every session feeling inspired to study on my own. My winter class had 7 students, and we were able to work with each other (without pressure) each week to tackle problems and collaborate on various subject areas.

I scored a 600 on my first practice test, which I took a week before the course started. It was demoralizing. However, Mark reassured me that my "stretch" target score of 730 was still attainable if I put in the effort. For me, the key was the way in which Mark guided our studying. Instead of assigning hundreds of practice problems, Mark showed the class how to focus on a particular set of problems and subsequently evaluate the strategies we used during the set. As a result, you learn how to identify problem types and solve them in a much more efficient manner, rather than blindly trying to solve as many questions as possible.

I never needed to cram for the test, nor did I ever feel like I was drowning in my GMAT studies. I studied for about an hour each day outside of the course--consistency is key, rather than trying to put in 4 to 6 hour days on the weekends. The course ended in early April, and I took the GMAT in mid-May. I highly recommend purchasing the add-on 1-on-1 "coaching sessions" with Mark, as those really helped me hyper-target areas of opportunity before my exam date.

In the end, I got a 740 on the GMAT, a full 140 points higher than my initial diagnostic test. Without Mark's wisdom and coaching, there's no way I would've reached my target score. For the sake of brevity, I'll finish my review by stating that this course opened up doors to MBA programs that I previously thought were closed. Thank you, Mark!

Through this class, I was able to hold myself to a schedule, follow a comprehensive learning curriculum, and gain tips on how to specifically ace the GMAT test format / CAT.

Materials - By going through the 10+ MP booklets and online videos, I was able to learn everything covered on the GMAT from the true basics to more challenging problem types. They offered a systematic way to identify and solve every type of problem so there was no mystery.


Teacher - Mark was great - he taught with succinctness / clarity and created a very comfortable classroom experience where every student felt compelled to ask any type of question and participate. You can truly tell he is a master of every part of the GMAT.

Classroom setting - I definitely gained more through self-studying afterwards than in class. The classes had people from all different backgrounds so we spent a lot of time covering really basic problems. However, the classes did help reiterate and cement some learnings.

Resources - Online portal was great, especially the Navigator tool that offered more detailed solutions to every single Official GMAT problem guide. The problem list was also good to target specific areas.

In the end I improved by 150 points and got above 700!

I started working with Mark after taking the Manhattan Prep 10 week course and scoring well below my goal (650 with goal of 700). After this, I decided to invest in private tutoring and started working with Mark Sullivan. I took the GMAT again, and scored 720 thanks to Mark (47 quant, 41 verbal). He quickly diagnosed my weaknesses, and then provided a clear plan to hit my goal. He focused on the biggest hitting items / content areas and devised a plan that I could manage with a full time job.
Outside of providing excellent tutoring services during my paid sessions, Mark was always available to respond to emails and provide feedback on practice tests. I never felt like I was “on the clock” – if we ran slightly over the time allotment, I didn’t feel that he was rushing to end the session. Mark was really a source of positivity and made me feel confident going into the test.
Very highly recommend Mark for anyone needing personalized tutoring!!! Just wish I’d started working with him from the beginning.

I had been trying to get done with my mba for the longest time by studying on my own but it just wasn't happening. A friend who had graduated from INSEAD previously advised me to join a course (which is what he did as well), and that was the tipping point! Being in a classroom setting really helped me personally. I felt challenged and engaged. I researched all of the programs available and felt ManhattanPrep was the one for me. They start with the basics but quickly build onto complex stuff. I was lucky that I ended up having the best instructor possible. Mark was engaging, super knowledgeable and full of tips on how to go about your prep. He was always available (even after the course was over) to answer any question you would have. I wish I had joined the course earlier instead of wasting a few months trying to study on my own!

I completed a 9 week course with Manhattan Prep in April and am very happy with the results! During the length of the course, we went from an overview of each section to detailed strategies to break down and attack each question type. Further we learned how to develop and implement a strategy to use on test day, which helped me to relax and perform at my best on the quant section.

I found both the in-person courses (where you are able to ask your instructors questions, get their in person advice on content, and work through exercises to improve your skills) and the pre-recorded video lessons (focused on teaching MPrep's strategies for each question type) to make a huge difference for me. The only complaint I have is the technology for the in person class, as it feels a bit outdated and I had trouble getting my microphone to function properly for the first few classes.

Overall I would highly recommend the course to anyone needing a high score for top schools, as they truly teach content and strategies that you can't track down on your own and that make a huge difference on test day!

For someone who is bad at self discipline, the Manhattan GMAT in-person prep class was essential for me. I tried the Kaplan online classes but had difficulty holding myself accountable. Mark from Seattle Manhattan GMAT was fantastic. The class size was small. Sometimes, there were only 3 students so it almost felt like a private session. I recommend taking the exam 2-3 weeks after the class is over so you don't lose momentum but still have time to do some last minute review. You should also take the exam multiple times to get yourself accustomed to the adaptive format which was the most difficult part of the test for me.

I first heard about this course from a friend who had taken it a few years back; he had raved about it, and he's a guy who rarely raved about anything. So, from the get-go, I was inclined to give preference to Manhattan Prep over any other companies. Still, at $2,000, I wanted to get a "taste" before fully committing.

One of the things I loved about this course was that I was allowed to come to the first session -- for free, no strings attached -- and check out the instructor and the overall vibe before plunking down the dinero. And about halfway through that first class, I knew I'd be handing over a bunch of Benjamins, but that I'd be doing it enthusiastically.

Our instructor was extremely bright, geeky about the material and the various ways to think about approaching problems, not at all pedantic (which is my biggest pet peeve with instructors/coaches of any kind), and he seemed to keep everyone in the room engaged. He was organized but not a stickler. There was room for questions. People were smiling and listening and stumped at times, and it was exactly what I thought this sort of class should feel like.

Over the course of the 10-week program, we had a clear syllabus outlining homework problems as well as topics to be covered in each class. As with most things in life, students got out of the program what they put into it, and in my case, I'll be honest and say that I didn't stick to the homework schedule...at all. Still, it was nice to have it -- as well as the accompanying boatload of books with practice problems -- for that inevitable time down the road where I actually decided to buckle down, SIGN UP for an actual GMAT test, and go back and do the homework the way I was supposed to have done it months earlier. Even though I didn't stick to the syllabus, the fact that I had one to refer to definitely helped was I finally got my act together.

The practice GMAT tests online and the analytics that go along with it are also super helpful. Manhattan Prep gives its students a granular look at their performance sliced and diced across all the different problem types. Super helpful for efficiently & strategically improving your game.

The whole company is also just good people. At least the four individuals I interacted with - either in person, on the phone, or over email. Not trying to nickel and dime you. Better customer service than your bank. Friendly and understanding people. And somehow they seem genuinely concerned with you getting the most out of the experience. A+ overall.

What else is there to say? These guys know their stuff, and they're here to help you hit your goals. I got a 720 on the real test two days after getting a 700 on my final practice one through Manhattan.

The GMAT class I took with Mark was wonderful. I thought it would be terribly dry, but Mark kept us engaged, despite it being for 3 hours on Wednesdays after a full day of work. My quant score improved dramatically and he gave us great insight into some of the tricks in mastering the test. Mark was always available to answer questions via email and provide practice CAT analysis.

The course itself was very good. The syllabus made sense and the content built on itself over the nine weeks. Overall, I highly recommend this course. I couldn't have hit the 700+ mark in 3 months without it!
