I took the test about a month ago and prepared for it by purchasing Dental Decks 2006-2007 from a guy a year above me, and bought two apps on my iPad. I felt that the decks adequately prepared me, but i noticed a few glaring errors in their content, plus carrying that heavy box around with me was a pain. First Aid's app had a good number of practice questions, but I felt the rationales were lacking in my opinion. Dental Boards Mastery felt really user friendly and had awesome pictures and mnemonics that I felt helped me understand and remember more. The statistics/analytics and practice quizzes in DBM were also really nice because the quizzes were automatically checked, plus i could see if i was going to finish on time.
