I am going to take Micro in the fall and I just wanted to get a head start over summer when I have all of this free time. I have a friend's Micro book as well as her Physiology book. What topics are emphasized the most in both subjects that you really need to know like the back of your hand for nursing? There was soooo much covered in physiology and I don't know what is used the most in the real world. I just want to get a head start while I still can:bugeyes:! Thanks!
