I used the Jepessen Private Pilot Manual for the basic information and a red "study
guide" for the cramming portion. I think the latter is by Gleim, but I'm not sure. In
any case, I see it at just about every FBO.

I studied the Jep book on my own through several months of my training. Read it
through several times. Then I went through the study manual, answering all the
questions over a period of about two weeks in my spare time. I was not real pleased
with the results; on the second pass, I seemed to do just as badly. So, I locked
myself in the house one weekend and did nothing but eat, sleep, and work the
questions in the study guide over and over again (I'm deadly serious about that). At
10:00 the following Monday, I was at the testing office.

I passed.
