Bertholy is long on doing and short on instruction. The drills are designed to teach you a classic golf swing without a lot of thinking. If you perform the drills as instructed, you will get better.
Don't be in such a hurry to move to the next exercise. Get the first exercise, then the next. Use video to confirm your corect positions.
Here's some links of some video I made -

It is REALLY important to learn how to disengage your conscious mind when you are executing the swing. You should learn how to play without THINKING ABOUT YOUR MECHANICS. Find a mental method or approach that teaches you how to do this. I recommend Clearkey ®.
