Hi everyone! I just took the OAT. Got a Total Science score of 360. bio 340 gen chem 360 orgo 400 physics 330 I basically just used the Destroyer. As someone who just took the test, I would highly recommend to get the OAT Destroyer. I went through the Destroyer a bunch of times, until everything was clear, and I came to the exam very prepared. Couldn't have gotten the scores that I did without it! I also bought top score cd but the only benefit I found that it had was getting comfortable with taking a computerized exam. Some of its questions aren't relevant and there are no explanations at all for the answers!
