Moe,
Congrats on commercial! That’s a tough one to knock out. For CFI school, my best advice to you is start making your lesson plans now. Figure out how you want to organize yourself, start digging through the CFI PTS and find the required topics you will have to teach in your checkride. Highlight them in the table of contents. Then note the topics you have to cover in that lesson and then just start taking down notes for that lesson plan. For example, runway incursions is a required topic. So find that topic in the PTS and then it will give you a list of items under the topic of runway incursions you need to talk about during your lesson. Start answering those questions on your own and jotting down a few notes and that will guide your lesson. Some people are very brief in their lesson plans, others like to create illegal points of all their talking points and some key facts. Remember you will get to use them in your checkride as a teaching tool, so out whatever you want on them to help you teach the topic well. The more lesson plans you can have made prior to starting, the more ahead you will be.
