For those who took the test in the past, what book materials did you find helpful to study for the exam when supplementing with KO/Hero (ie first aid, board busters, etc)?
Based on the feedback we've received from students who took the exam last year, we'd highly recommend using First Aid or Board Busters to help lay a foundation. Keep in mind, the ADAT is a bit more selective with the type of content they like to test so try not to get bogged down by the minor details that you may come across in these resources.
