One of the reasons some students don’t perform well on the Dental Aptitude Test is because they don’t study from DAT preparation materials that are up-to-date.
The syllabus covered on the DAT exam changes over time, and some publishers simply don’t update their preparation material to keep up with changes in the DAT syllabus. You want to make sure you don’t end up studying from out-dated material that’s not covered on the DAT exam.
