I found this book extremely frustrating to use. I found an average 1 mistake per page, causing me to question every word written. As examples, according to this book, Vitamin D is 25 hydroxylated in the kidney (should be liver), alzheimer's has equal prevalence in males and females (F=2M), classical C5 convertase is C4b2b3b (should be C4b2a3b), Myesthenia Gravis is a result of desensitization block of Ach receptors by autoreactive antibodies (antibodies do not act at the ligand binding site, but serve to cross link receptors --> increased internalization), and this is just to name a few.I recommend choosing another book for your studies.
