I am retaking the DAT in order to improve my O-chem score. Does anyone know of any good study materials that are aimed at just this part of the DAT. Thanks.

Honestly, I think the Kaplan does an adequate job. Just memorize everything from the large Kaplan book for the O-chem section. There is also an MCAT book that I recommend. It's called 1001 O-Chem problems by Examkrackers. www.examkrackers.com. You have to order it from their website. It's the only way to purchase it. You will get plenty of practice from that book.

Let me know if you need anything else.

I used mostly my old college texts (solomons) and Princeton review problem books. I did pretty well so I think it works.
