Biology: Go to book store, get the SAT II subject for Biology of kaplan, trust me...the tips in these book are very very very alike to the test....The material is used for high school students; thus, it explains better than any books from Kaplan for PCAT or MCAT....I went to bookstore everyday, and enjoyed my readings [did not study]..this book also has quite good practice exercises. [you may need a littl more from your biology book, but not that much] ..I got 21% for first time with no reason, 53% for second time, just review a little, but for third time, I did not study anything but enjoy to review this book, and I got 83% for Bio section...
Chemistry: [ I am chemistry tutors, and I am sure this will help you to get a good grade. Go to grab the Barron Book for PCAT [the newest editions]...The practice is quite similiar to the test, although it is quite easy but it is what it is in the test...It wont be difficult for the questions in the test but just need to understand the most basic how to do it....For organic Chem, trust me, review the last sections in the General Chemistry book, they are from there a lot..Make sure you know how to name structure, understand some basic reactions..you will be fine...I got 95% for first time, 97% for second time, and 99% for Chem section in the last time..
Math: I did not do any review for this because I am a Math Tutor also....Thus, I found that got the problem quite easy...but, for suggestion, do practice in Barron Book, it is good....do review for Tangent line, how to take basic derivative [ the slope of tangent line], point slope formular [ how to find equation of line], basic logarithm [ ln, log, basic calculation for it], Basic simplify, rarely for convertion but not too difficult, how to simplify fraction, how to FOIL (need to be quick), how to do the words problem like the timing [ example, if one works for 1 hours, the other one works for 2 hours...how long they will work together to finish one jobs], or distance [ application of Distance = Time * Velocity], or Filling volume [ a tank consumes 2 gallons of gas for 5 miles, if the full gas tanks can drive for 5 hours with the speed of 15 miles per hour. How much gas does the tank can contains]...Those are basic questions which will appear in the test all the time... For statistic, just focus on the "meaning" of Mean, median, average, and standard deviation...that is good enough....Take it fast but accurate..PCAT is not difficult but how to be accurate in the short amount of time...
Vocabulary: Go online, and buy this book, it will definitely help, 501 vocabulary analogy words [very helpful for analogy part], if u want to improve more, go online to search for some practice for GRE...it is qutie similiar to PCAT analogy...Or if you want to improve in the fill in the blank, go to Get SAT review from Kaplan...they are very very very alike....
Reading: Get the PCAT from Kaplan, it will help to have some practices, remember, the answers are always in the passage.....
