I took the Cheetah PMP Certification course just prior to taking the exam, and receiving my PMI PMP. The instructor was extremely educated and up to date on the PMP exam, and the best way to prepare for it. He helped explain what was important to write on our fact page that we were allowed to bring with us when sitting for the exam. He helped us focus on how to study, what was important to study, and how the exam was structured. I took Cheetah's course because it was highly recommended, and they didn't disappoint.
