The Origin

Dear reader:

What a pleasure that you made it to this blog post.

What is this page?

Chances are that you already know what this website is about: It was built to assist prospective GMAT test takers in their preparation.

Just two years ago, I went on the GMAT-journey myself and was struck by the seeming oligopoly in the GMAT-prep market. Many of my friends opted for the ubiquitous GMAT Tutor, offered by the economist [1]. While certainly a great piece of pedagogical material, the price tag of anywhere between £799 and £999 is a distortion to say the least. Similar lines of argument hold for things like the Manhattan Self-Study toolkit [2].

Regardless of ones personal taste regarding any one particular offering, all products comprise at least two main components: Learning & Practice. While the required levels of mathematics and English are not particularly high, almost all providers offer some form of audiovisual recap of high-school mathematics. This treatment should re-familiarise the prospective test taker with topics ranging from prime numbers to geometry, and facilitates practicing in the first place. Aside from this, all offerings include a library of carefully crafted questions that allow the student to apply the newly acquired knowledge.

While the inclusion of these two components makes intuitive sense, there seems to be an imbalance between learning and practice in almost all GMAT-prep products. Almost all products take great care of explaining the mathematical concepts, but offer quite small question libraries (e.g., does Manhattan's Challenge Problem Archive only contain 250 questions [2]).

After talking to others having done the test, and taking the GMAT myself, I can say with confidence that the single most important determinant of score is the test taker's routine. Especially candidates aiming for scores beyond 700 need not waste time on thinking about easy problems. Instead, such advanced test takers typically know the right answer to a question as soon as it shows up on their screen.

By abstracting away from individual questions, creating recipes that cater towards different learning goals, the GMAT-Trainer can generate a virtually infinite number of questions. After only a few weeks of calibration, we have spanned almost all learning goals set by the GMAC for Problem Solving questions and are on our way to do the same for Data Sufficiency problems. Among other sources, we use GMATClub, an excellent discussion forum for all things GMAT, to identify abstract learning goals and potential wording.

Who are we?

Everything on this website: design, code, and contents were developed by a small group of (former) students of WHU – Otto Beisheim School of Management and the University of Oxford. Almost all of us have done the GMAT at some point of our lives and quite a few of us used the technology on this site to prepare for our personal test days.

While some of us now work in professional services or higher education, some of us still actively maintain this project.

Where will the journey take us?

Until now, this platform was an internal studying tool – which we now decided to take online. We are far from being done with developing the product and welcome any and all criticism. Let me share a few milestones that we hope to reach in due course:

  • Full support for Data Sufficiency questions
  • Full support for Verbal (mainly CR & SC) questions
  • Virtual testing mode, looking only at the individual testing session
  • Extended analytics and peer benchmarking

Thank you for taking the time reading this article. Should you want to get in touch, please do so at d@gmat-trainer.com.


Have a wonderful week.
