The first time I took the DAT, I didn't take Kaplan...studied on my own and didn't do so well. Before I took it the 2nd time, I took the Kaplan review course, and did better. My Kaplan course was an hour away too. But overall I thought it was worth it. I agree with DMD_hopeful...the class was a bit useless, but not completely. At least there was some thing that I was able to get out of it...and to me that was worth it. To be able to get that extra point on the DAT could mean the difference between a 19 and a 20.
The most important thing is the subject tests and practice exams they offered. It doesn't matter how much facts you can store in your brain, if you aren't prepared by the way they ask questions then that can hurt you. So the practice tests/subject tests can do just that.
Again, it's a matter of what you think you need. People do just fine without Kaplan, but there is a nothing to lose....well, a few buck $$. I say use all the resources that are out there because you don't really want to think back and say, I really think that Kaplan course could have helped me. Hope that helps.
