Zahn helped me build a solid foundation of the material through the scope of the often-complex question structure of the exam. It's IMPERATIVE to handwrite notes while working through the pre-study so the Live Review can truly be a review. I highly recommend taking Brandon Truitt as he's thoughtful in his explanations and provides a test-writers perspective to help coach you through answering questions. His pneumonics were incredibly helpful when memorizing certain topics that were a bit harder to grasp. Zahn for the win!
