I couldn't agree more. I had form CT. Out of the six or so bio sections there were two passages that stressed the immune system. I felt like I knew a wide range of material quite well, yet the MCAT somehow managed to focus on such a small scope of the required topics. Very frustrating. Like you said, no hormones, no excretory, only one nervous system question (sympathetic vs. parasym), no embryology, little respiratory/circulatory, little digestive, etc, etc, etc. It seems unfair to cover such a narrow range of material.
