I don't know about the ECE exam but i know when i was in school and took my psych nursing exam and final and i kinda just skimmed through the psych book most of my studying came from the Psych sections of many different NCLEX-RN practice books. This time of year is perfect as many recent grads are preparing for NCLEX-RN just go to barnes and nobles or the like buy a coffee or something in the cafe and sit there and use their books for free. I personally bought my favorite to use at home but different books sometimes have items others didn't so i would go to the book store to look at other books without paying $50-75. Trust me they don't care I spent 6 weeks going to local bookstores basically using their practice books for free (well i usually bought something in the cafe (lunch or coffee) but hey i buy a coffee daily anyways).
