Some Things You Should Know Before You Begin

Omitted PS Answer Choices

On many Problem Solving questions (ones that are normally multiple choice on the GMAT), I have chosen not to provide answer choices. This is an intentional decision. I have done this because:

  • I believe that if you want to get a very high score on the math section, you need to learn to find the answers to Problem Solving questions on your own, without leaning on the provided answer choices as a crutch.
  • Without answer choices, you are forced to try to come up with a way to answer the question.
  • This encourages critical thinking, and it can make it clear to you that you need more practice in a given area.
  • Of course, on some types of PS questions, answer choices are necessary. In those cases they will be provided.

Omitted DS Answer Choices

I have also not chosen not to list the answer choices on all Data Sufficiency questions. This, too, is an intentional decision, with a more simple justification: you need to have the answer choices memorized. If you don't yet have them memorized, please see the Data Sufficiency section of the site.

Text Instead Of Math Symbols

In order to make this product as straightforward as possible and to allow every question to be presentable in a text format, I've decided to take a few shortcuts with math terminology. Specifically, you will see the following:

  • Use of the word "pi" to represent the Greek letter with the same pronunciation.
  • Use of the caret ("^") to represent exponentiation. So, 2^3 means "2 to the third," or 2*2*2.
  • Use of "root(x)" to represent the square root of x. So, root(4) means , "the square root of 4."
