How similar is DAT and OAT DESTROYER to the actual  exam?

It is very similar in content to the actual DAT and OAT Exam as Dr. Romano has interviewed his many students that have already taken the DAT and OAT. The questions are slightly more difficult, but the explanations are very detailed and clear. Practicing these solutions will allow you to handle a wide-range of potential questions.

First, let me say, there are no "DAT or OAT SECRETS." No one can give you the exact problems. We are showing you how to build a foundation that will help you achieve a high score on the DAT. Ask any oral surgeon, periodontist, or prosthodontist about secrets to achieve success and I am sure that they will agree that there is only hard work, perseverance, dedication, and proper preparation. If you know all of our questions and study, it will give you a good foundation in the basic sciences.
