Okay this is how I studied: for the sciences, I read through the whole Kaplan prep book - did all the practice section questions - did all the online kaplan courses - and did all the online quizzes and workshops. Also, i read through most of the DAT Destroyer 2009. I studied from 10AM to about 11/12PM. Also, i'm a chemistry major.
For math, same deal as about for the sciences, however i didn't do all the section quizzes online.
My basic method was read read read, and take practice quizzes and tests. I woke up around 10 and then studied all day with food breaks.
For the practice tests, I pretty much took one fri, sat, sun. I saw my score increase each day, but used each test to see how I could improve my score. Fri i made sure to get better timing and ear plugs. Saturday, my timing was up, but my sciences were down I made sure to take less notes on RC. Sunday, everything was up and i did awesome. Felt prepped. Then today, day of the test, i leafed through a few things I didnt' want to forget, and took the test. I didn't feel 100% confident, but I am going back to school and have a lot on my plate for my final semester and wanted to take the test to get it out of the way and make sure that I could retake it in April, if need be, so I could still get my applications in early.
