Let's talk about checklist. It's available though many websites. http://www.accessibleaviation.com/T-6%20Gouge/Callouts_Checklist.pdf

Before we solo, each step is required verbalization. Each yellow step requires exact phraseology and acknowledgment from Instructor Pilot. Knowing each step from memory is highly recommended or IP might get mighty ticked off due to wasted time. Add to that exact radio phraseology. Practicing for this is preferred while under stress to simulate flight conditions and allow brain to adapt. A lot of students sit in front of a T-6A cockpit poster and practice checklists during their free time.
