The More the Merrier
The more questions you practice, the better chance you have of passing your exam. I highly encourage all Six Sigma exam candidates to gain exposure to as many problem questions as possible.
The exam is particularly tough, and thorough test practice is vital for success. That includes taking an ASQ practice exam when your studying for an IASSC exam, a Villanova exam, or any other kind of lean six sigma black belt exam.
