You should be studying outside resources on your own, any way....."Weather Flying" by Robert Buck, "Instrument Flying" by Richard Taylor....etc.

When I took instrument ground school, I read ahead. I also sat in the back of the class, and having read ahead, spent the class time reading the next chapter, treating the class as "enforced study time" as the teacher was boring. But I was also listening, and getting reinforcement/reiteration on areas that needed clarification. But when he asked a question, I usually had the answer, or when I had a question, it was a good one, while it was obvious many hadn't read the chapter at all. Makes you look like a genius...

I agree with the above poster about the new instructor....The private student who is the FIRST zero-hour student of a new CFI will often get more dedicated, thorough, exacting, and loving attention than you would think...

You make your own luck. Depend on yourself, but get the sign-off and the credits.
But give the guy a break, he DOES know more than you.... your job is to turn the tables in one semester.
