What’s on the Exam?
First, let’s talk about the questions on the exam. There are 110 multiple-choice questions total, but only 100 of the questions will count toward your score. Why is that?
The 10 unscored questions on the exam are called “pretest” 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 pretest. They’ll appear just like the scored questions throughout the test.

Exam Scores
The test is scored using a scaled scoring method. Here’s how it works:
For every question you answer correctly, you get one point added to your raw score. At the end of the test, your final raw score will be converted to a scaled score. This scaled score will range somewhere between 100 and 750.
The reason your raw score is converted to a scaled score is because everyone who takes the test is given a slightly different set of questions. Since everyone has a different arrangement of questions, and because some questions are harder than others, converting your raw score to a scaled score ensures a more even playing field.
Retaking the Exam
If you didn’t get a passing score on your first try, that’s okay! You can retake the test after submitting a new application.
Keep in mind that you will have to pay the $269 retesting fee for each attempt.
What Test-Takers Are Saying
Don’t just take our word for it! See what real test-takers are saying about the Six Sigma Green Belt exam:
“The exam’s questions were primarily project management and definition-based. About 20 questions were on probability, statistics, and capability measurements. I brought a calculator and used it on about 10 of those questions. One mildly interesting thing I noticed was that my exam had no questions on the Quality Gurus or Central Limit Theorem.”

“In my opinion, the math is not difficult. I didn’t even use z-table, t-table, etc., because the test provides all of these values (but I think you should prepare them).”
Imaginary_Dog_1692
“The exam was very definition- and concept-heavy with about 10 questions that I needed to do basic calculations on or interpret data from graphs/tables. Overall, you kind of need to use some critical thinking/logic to answer the questions.”
heartywineburger
“The scratch pad function only allowed typing, so I couldn’t handwrite notes with my mouse/touchpad. That made it a little more cumbersome when writing out formulas and the plan I had for solving for specific variables. There was a calculator with basic and scientific functions available but I used my own calculator.”
