<p>Campbell-Reece is amazing. I basically lived off of this book since our bio teacher was not that great. People kept on wondering how I aced her extrememly hard tests – it was because I sat myself down and absorbed 3 chapters at a time for about 8 hours the day before her tests. XD Not the best method… but I retained most of the knowledge. Made a 5 even though I knew nothing about human anatomy/physiology/ecology/lab stuff.</p>
