Achieving a six sigma certification isn’t everyone’s goal. But many people do pursue one. If you are going to study for a six sigma exam, I’m here to help!

Three Ways Six Sigma Study Guide Can Help You Study

Free Practice Exams

For those that are studying, I cannot stress how important it is to practice as many different types of questions as possible. Taking self tests are the best way to assess your preparedness for an exam.

I have a page of links to free Green Belt and Black Belt practice tests. If you find others, please let me know and I’ll put a link to them.

Answers to questions

I am providing answers to the questions of the free tests on the site. If you get stuck on a problem, or do not know why the correct answer is the one they list, just use the search function on If you search with either key words or with the question text, the article with the right answer should appear.

If it doesn’t or if there is a practice question that you are struggling with, you can post it in the comments section of any of the pages and I’ll do my best to answer.  I ask that you do this publicly to avoid people sending me ‘take home’ quizzes.

How I Studied

Each exam is different. For example, the Villanova Black Belt exam is an on-line, open notes test. The ASQ Six Sigma Black Belt exam is open notes, but you cannot have any example problems in your notes – plus no electronic medium is allowed, just paper notes.

Each kind of test requires a different study protocol to make efficient and effective use of your time. You can see how I prepared for each here:

Hope this helps!

    What about the exam preparation for IASSC Green Belt ? Does it has the same exam format. Also do the sample question papers you have mentioned reflect IASSC exam ?

    • Hi Karthik,

      Yes, the sample exam I have built incorporates topics from IASSC as well. I believe the format is the same.

      Note the IASSC exams are not open book. They give you a referential document with formulas and a scratch sheet.
