it's so easy...cavemen pass regularly
I took the class for the first time a couple of weeks ago. The instructor reviewed the group of people doing renewals (1/2 day required) which in turn exposed the rest of the group to "test type questions". Basically answer the most politically correct and common sense answer to get it right.
As far as shooting, as long as you make all your shots from 5 yards and 7 yards within the scoring rings, you can miss all of your 15 yard shots and still pass.
The class is a learning experience to be enjoyed with an open mind. There is no need to worry about it.
I would wish you good luck, you won't need it.
