Kaplan's Five Basic Principles of Test Expertise
Learn to Recognize and Seek Out Questions You Can Do
Another thing to remember about managing the test sections: PCAT questions and passages—unlike items on the SAT and other standardized tests—are not presented in order of difficulty. There's no rule that says you have to work through the sections in any particular order; in fact, the test makers scatter the easy and difficult questions throughout the section, in effect rewarding those who actually get to the end. Don't lose sight of what you're being tested for along with your reading and thinking skills: efficiency and cleverness. If organic chemistry questions are your thing, head straight for them when you first turn to the Natural Sciences section.
Don't waste time on questions you can't do. We know that skipping a possibly tough question is easier said than done; we all have the natural instinct to plow through test sections in their given order. But it just doesn't pay off on the PCAT. The computer won't be impressed if you get the toughest question right. If you dig in your heels on a tough question, refusing to move on until you've cracked it, well, you're letting your ego get in the way of your test score. A test section (not to mention life itself!) is too short to waste on lost causes.
