## Part IV GMAT: Math Practice Test

### Chapter 11 Quantitative Practice Section

INSTRUCTIONS

This practice section contains 37 questions covering a range of math topics similar to those you will see on the real GMAT. It recreates (as much as is possible on paper) the experience you will have in taking the Quantitative section of the GMAT. Set a timer for 75 minutes and try to answer every question in that amount of time. The answers can be found in Chapter 12.

A few reminders:

· Start slowly; then gradually pick up speed to finish the section.

· Do the questions in order. You must choose an answer before you move on to the next question, and you cannot go back to a previous question.

· Set up your scratch paper and use it to do all of your work.

· Important: Answer every question, so you may have to guess on some of the tougher questions.

· Use the methods and concepts you have learned, especially elimination methods and the various versions of Plugging In.

· Remember: In the data sufficiency questions that you’ve worked on throughout this book, we removed the five answer choices since those are always the same. Here in the practice section, we’ve added them back in, since you will see them on the real GMAT.

The section is designed to simulate the performance of someone who gets about 75% of the questions right and receives a score of about 40 (on the 0−60 scale).

Good luck!
