ICYB mock tests are not only reasonable but are also backed by a safe and secure payment system. I did not face any kind of problem while paying for the practice questions. They gave me the right kind of environment to practice for the actual IASSC Certified Lean Six Sigma Yellow Belt certification exam. I have recommended the tests to many more aspirants who wanted to clear the exam at first attempt.
Secured payment system
