It’s time to test your skills on passages that have actually appeared on real GMAT exams in the past. You can find passages in The Official Guide for GMAT Review (2016 Edition) (pages 27–32 & 366–418) and The Official Guide for GMAT Verbal Review (2016 Edition) (pages 22–60). To best make use of your Official Guide problems, we recommend tracking your work in our GMAT Navigator tool. You will be able to record the time you spent on each problem, the answer you chose, whether you guessed, and whether you want to redo the problem in the future.

Do one passage at a time, or build a mixed set that includes Sentence Correction and Critical Reasoning problems. Here’s how to get the most out of each passage: 1. Give yourself approximately 2 to 2.5 minutes to read shorter passages and 3 minutes to read longer ones.
Spend about 60 seconds to answer General questions and about 90 seconds to answer Specific ones. 2. On the real test, you will see only one question at a time, so don’t look at all questions before reading the
passage. 3. As you read the passage, tell yourself the Simple Story. By the time you’re done, make sure that you can
articulate the Point and that you have a rough Map of the passage, either on paper or in your brain. 4. If the passage has more than 4 questions, answer only the odd-numbered questions. You’ll do this
passage again sometime in the future; the next time, you’ll answer the even-numbered questions. (The real test does not give more than 4 questions per passage.)
5. Follow your four-step process for answering questions. (1) Identify the Question (2) Find the Support (3) Predict an Answer (4) Eliminate and Find a Match
6. To keep it simple, use these guidelines when studying from OG books:
Shorter passage, 3 questions à about 6 minutes
Shorter passage, 4 questions or
Longer passage, 3 questions
à about 7 minutes
Longer passage, 4 questions à about 8 minutes

Mental stamina: do IR + essay. The test will feel harder.
Mindset: “...but I should know how to do this!” (No! Let it go!)
The test might not reflect actual improvement
You may mess up the timing. You may be more mentally fatigued due to IR + essay. Your score may not get better (or might even get worse).
That’s okay! You’re still improving even if your overall score doesn’t go up yet.
