That assumes a competent and standardized training department, where the people testing you aren’t asking dozens of questions that aren’t covered in the reading. If you only study what they give you, you will fail your oral at ZW. The problem is the “kinder, gentler, we aren’t asking you to build the airplane” mentality has hit Indoc and systems ground but not the examiners.

Find a PRM and some gouges once you’re in the schoolhouse. Study roughly twice the depth they tell you. Right now worry about the ATP written, then hit limitations from FCM vol 2.
