One more thing I would do is mark topics in the books you take with you to your ride. I use those little red, yellow, or blue self adhesive tabs that you can right on, they are perfect for quick referencing.
The reason I say this is because on my first CFI ride, I told the examiner what I knew about a tetrahedran, and was right, but when he asked me to prove it to him. I looked in the index of two books before finding the right one. As I was turning to the right page I was handed a pink slip. I know now that he shouldn't have failed me, but I didn't know better then. Now I would protest it. The point is if I had found it quickly we would have continued on and maybe passed. So mark your reference material well.
Also, take many many books and keep in mind that the FAA isn't too hot on books that aren't written by them. I should say some FSDO's aren't too hot on books not written by them.
