on the PCAT blueprint for 2012-2013, it states 17% of biology section will be pertaining to Diversity of Life forms, what exactly does 'Diversity of Life forms' covers? On pCAT website, it clearly stated there will no questions on non-human biology, including plants and animals. so does that mean no questions on photosynthesis? http://www.pcatweb.info/PCAT-Updates.php 20% of biology section will be microbiology, would mcrobio we learned from intro to biology covers all contents in microbiology section of PCAT, or are they more close to what a microbiology class covers? Are there any spectroscopy problems? Does Dr Collins's study guide have updates to accomdate changes to the PCAT? I noticed Kaplan and princeton's still include some materials no longer tested.
