I took the test last year. The test can be very confusing sometimes. You really need to understand the concepts that the question deals with. I found a few questions where I had to choose between two answers that I thought were right.
Read the question, if you cant answer it, mark it for later review, and comeback to it later. (The test was on computer and there were many options to skip/mark for review). The test proctor told me it was the fastest she had ever seen anyone take it, which suprised me cause I took my time by skipping the hard questions, then coming back and answering the hard ones, and then again reviewing every question. She also said more people fail it the first time then pass it.
I took my time, was VERY prepared (practice tests, reviews in the book, I never marked answers in the book, that way I could always go back and take the chapter tests and reviews again later)
Of the 3 other appraisers I work with, I am the only one who took his course work online. While my course was very broad and in depth, theirs were focused by the instructor's knowledge of the test and what areas of study to focus on. Even with that knowledge they said they struggled too.
As for trainee hours, my company's policy is experiance begins after passing the test and recieving the Trainee Liscense. Boss wasnt sure about that specific law, but said by doing it this way all "corners are covered" with clients.
One thing I learned is that 90 percent of the course work is background concepts, and that I use only 10 percent on the job. Course work doesnt tell you how to actually do a report, or even what one looks like! But neither does the test.
Good Luck, keep your head up.
