I only did kaplan for gen chem and I was feeling Very uneasy about this section (highest score on practice test was a 17). I took the DAT today and could not believe how basic it was. I scored a 22, and actually thought I did better. If you are using those materials you will be very well prepared. oh by the way there was absolutely no math, mw were given and the the answers were just how to set up the problems.
