What’s on the Exam?

Questions: 200
Time limit: 4 hours


First, let’s talk about the questions on the exam. There are 200 multiple-choice questions total, but only 176 of the questions will count toward your score. Why is that?

Unscored Questions
The 24 unscored questions on the CHST exam are called “beta” questions. These are added to the exam to determine if they’re good enough questions to add to future versions of the test.

The trick is that you won’t have any way of knowing which questions are scored and which ones are beta. They will appear just like the scored questions throughout the test.

The time limit for the exam is 4 hours. There aren’t any scheduled breaks, but you’re free to take restroom breaks as needed.

Let’s take a closer look at the different sections of the CHST exam.
