Sunshine, from my research, a lot of people on SDN will tell you that unless you have a really good science background, Kaplan is unfortunately not complete enough to prepare you for the DAT. Sorry to tell you this, but I read so many bad reviews of Kaplan that I avoided it in my study plan.
Most of the people here on SDN who have done really well on the DAT do self-study. Many people have posted "breakdowns" of how they prepared for the test to get great scores:

Right now, what I would do is start a very rigorous 2-week review plan that covers the following material:
Chemistry: Chad's video lectures for the DAT ($115): used by HUNDREDS of people here to get a really concise review of GenChem and OrgoChem. It's got legendary status here and is by far the best investment you'll make for chemistry reviews. You find these videos on coursesaver.com.
Biology: Cliff's AP Biology ($10): Cliff's will cover most of what you need and many people agree it's just thorough enough to be effective review material.
Then, you can use the following material to practice:
Overall Practice: DAT Bootcamp ($97): This is the best practice material out there for almost all sections, and the PAT practice is great.
Look at the attached study schedule to see what a 2-week review of Bio, Gen Chem, and Orgo Chem looks like. It takes discipline but it's definitely doable. This is the schedule I used to get a 24 aa/25 ts/26 pat.
