SO basically I will start studying for the PCATs once I buy my books. I have basically 5-6 months to study for the JUne 2009 exam. Never taken the exam before. I actually dont remember any organic chem, calculus, or biology. Literally a blank mind.. I Know the test has changed from 2007 but i saw real cheap old versions (2006) books of barrons and kaplan for like 3 dollars online at ebay/amazon. Would it be useless to buy those books just to review concepts becuase the concepts dont change. Will be using my old bio, ochem, and calc textbooks. And as for real test practice, use real exams from Cliffs or Pearson or buy the updated new Kaplan 2008-2009. Or should i just dish out money for new updated books altogether. How has the test changed from 2006 to now? Is it the number of questions, different topics?
