Thanks for your question. There is a vast number of skills and content areas that the GMAT will test at a very high difficulty level.
The Quest for 750 - Advanced Quant was born of a number of MGMAT Instructors attempting to identify certain principles that occur repeatedly with harder math questions. There were a few principles that seemed to appear in the experience of many Instructors (for example, Identifying a Pattern in a series of numbers). The Quest for 750 - Advanced Quant attempts to identify and explain 3 of these principles.
However, due to the vast number of math questions, you should not take the Quest for 750 - Advanced Quant workshops to be exhaustive. If anything, the principles might apply to a small handful of the questions that you’ll see on test day (i.e. 1 - 3 of the 37 questions). Unfortunately, there are no principles that will apply to every hard math question.
The same is true for the Quest for 750 - Advanced Data Sufficiency. Both Quest workshops represent the common experiences of our Instructors, but both will still only apply to a small handful of math questions that you’ll see on the GMAT. The best way to study for the GMAT, and to get a high score on the math, is to review all math principles in their application to Official Guide GMAT problems.
