Does Zach Stone course teach material not on the exam?( PE: Power)

Little context; I’m still in school set to graduate in May and then take my exam after I graduating. I haven’t worked in the industry that has taught me real world knowledge.

I have been study the Zach Stone course for about a month and I see a bunch of people say how helpful it is I feel I have learned some but not as a crazy amount just yet.

I have noticed that some material mention in the on demand course has not been in the PE handbook.

So main question is, is that true? That he teaches material not actually needed for the exam? Like if it’s not able to be found in the handbook is it going to be on there (besides super basics stuff).

Then what would yall suggest to be the best way to learn through practice problems using Zach Stone course? I want to wait go practice exam once I finish the material so I can do it all in one sitting and see my percentage of correctness.

Hopefully this makes sense. Thanks in advance for responses.
