Studying for any graduate-level standardized test can be extremely difficult and time-consuming if you're not the test-taking type. Taking the DATs for dental school is no exception, and I tried very hard to find a better way to study for this test the second time around.
Fortunately I came across AM Tutoring, and I can say for a fact that my score not only improved to the place I needed it to be but that I also understood concepts far better now than I ever did in college. The services were very flexible around my schedule, and, with a few minor adjustments and switches, I was given a very knowledgeable and understandable team of tutors to work with.
Although I highly recommend using this service, there are definitely guidelines to consider before signing up. First of all, you MUST HAVE TIME TO STUDY, especially for graduate-level tests! I can't stress this enough. There is a LOT of work to complete prior to your tutoring sessions, and I feel that it's much better to be overprepared than underprepared. In the 2.5 months time frame that I had to study, I was working two jobs for about 30 hours per week, with 20 hours or less of study time. For this kind of tutoring, I would recommend setting aside more time to studying, possibly a whole year, and minimizing your work life as much as possible.
Second, expect to be pushed to your academic limits. I had material that covered all of my subjects, but the key to learning and getting better scores is repetition... repetition... repetition. Your tutors will challenge you mainly on the concepts, and any questions you have will be answered to the best of their ability, but it ultimately comes down to how much effort you want to put into this.
For the money I invested and the knowledge I've gained, I'd say this tutoring was well worth it. Whatever test you study for, expect success with this service... but don't expect it to be easy.
