You don't need expensive board review books for the written exam (read up on all the subjects from the ABA ITE Content Outline), but the Ho books are very good for the oral boards. Buy/borrow used, 2003 version is good enough.
Jensen is for people who need their (pretty shallow) review book to sound like some crappy motivational speaker.
They seemed to be a big waste of money. I didn't use any of them.Anyone take is for written boards? Please comment. Helpful? Waste of money?
