I remember having to drive to the Spokane FSDO in the late 70's to take my PPL. This was before proctored exams were available at CWU in Ellensburg. I remember sitting in a room by myself at a big table and the room was all windows, allowing the FSDO guys to keep an eye on you lest you try to cheat. You were given a binder that was the written test bank and were given a computer printout of the random question numbers you had to answer. I was like 16 and had driven all the way from Wenatchee to take the test, so it was a little intimidating.
I do remember ASA had a written test guide you could buy that was an approximation of the FAA's test bank. That was a huge help in knowing what to study.
