I took a variety of practice tests. I took the two from Pearson, Multiple Kaplin pre-tests, and even some DAT and MCAT pre-tests. Obviously the DAT had stuff i didnt need on it so i didnt worry myself with those sections. Kaplin is a great study source. If you have the money for it and for the classes do it, i didnt but i here its well worth it. I also used a flash card system to help me review on all the subjects. It was very useful for brushing up on forumalas and what their names were for the Chemistry section.
