Hello everyone,

My name is Gilad Pagi, a Ph.D. student and a math instructor at the University of Michigan, and the creator of the prep course

Lately, I was informed that throughout this forum you may have found a few posts referring to the course and/or to myself, many of which give the absolute wrong impression.

Let me start by saying that GP Group’s is a legitimate website, a well-thought course, and a result of 1000+ work hours. To this date, more than 200 students have already taken it.

This account, and this account only, is the official account for SubjectMath. Please disregard any other users speaking on my or on my course behalf.

At the beginning of my way in this business, I made the unfortunate decision of purchasing and outsourcing internet advertising services and SEO management services, in order to allocate all my energy towards perfecting the course and book content. The result was the usage of my good name and credentials in advertising techniques which I did not approve. Many of you pointed out the sketchy nature of those techniques and I hereby offer my sincere apologies. Of course, those advertising services and individuals are no longer working for me.

Nevertheless, I stand behind the material. This course is only designed to help future mathematicians. There is no scam, no ploy, only helpful math for the GRE.

The video modules are published on and the textbooks are published through Therefore, all of our materials are backed by their magnificent customer service and their policies(see here and here). If you are not satisfied, you will get your money back.

There have been concerns regarding the reviews authenticity on Amazon. We can assure you, the positive reviews you currently see on Amazon and Udemy were written by satisfied students and customers sharing their experiences.

I welcome you to comment I will address any question or concern.

I wish you all good luck in your studies,
All the best,
Gilad Pagi, Creator
