And if you complete every lesson for your certification body’s exam, score 90% or better on each of its quizzes, score 90% or better on at least one mock exam on your first try, and still don’t pass your exam, send me your score report within 30 days of the exam and I’ll refund you: the full price on an annual plan, or your last payment on a monthly plan.

What students say

How it works

You don’t need to get every question right to pass. You need enough points. Take the pre-assessment, and the course shows you which topics are worth the most points for you. Study those first, check your progress with the subject quizzes, then prove you’re ready on the mock exams.

If you have a question about your exam or whether this fits it, email me at ted@sixsigmastudyguide.com. I read every email.
