Dear future ODs:

When it comes to finding good preparation material for OAT, per-optometry students are at disadvantage compare to premeds . For the past few years AAMC has releases a number of their old tests. Since these materials reflect the real MCAT, test preparation programs such as Kaplan, Princeton, ExamKrackers, Arco encourage their students to judge their performance by the AAMC exams, despite the fact that these test preparation courses have numerous of their own full length exams for their students to practice with.

Unlike AAMC, the perparation materials that Association of schools and Colleges of Optometry ( ASCO ) has released is limited to the materials that comes with the application which is not even a full length exam. Thus, we don't have any full length exam that is coming directly from ASCO that we can use to see how well we are prepared for the actual OAT. The OAT prep books that are on the market some of them are too easy and some of them are too difficult.

My purpose in writing the above message is not to complain or to agonize, but to find a way so we can help each other and our future collages who will be taking OAT in years ahead. I encourage anyone who has taken the OAT or planning to take the OAT share their knowledge of OAT under this post. The following is a list of all the topics that is a fair game on OAT provided by ASCO . ( I have to admit the range of these topics is very wide. It is so wide that it covers the entire text book of each subject. If you can recall anything that is tested specifically by OAT share it with everyone.

  1. Dentist
That message is well-informed and appreciated, however this is the pre-dental forum, so it isn't of much help to anybody here. You probably ought to post that message in the Pre-Opt. forum, if you haven't already done so.

The only link it has to dentistry is that the American Dental Association writes the OAT, and therefore the OAT is extremely similar to the DAT.

Good luck with your plans for optometry (and don't feel shunned if nobody responds to your post!) :D

The DAT is similar to the OAT, except that the DAT doesn't have physics and the OAT doesn't have the PAT. I guess that you can use the released DAT to study for natural sciences. Tough luck.
