What is Histology? I have had a people tell me that is would be essential to take it while I am an undergrad in college. That is would help me when I enter med school. They even said if you take it as an undergrad that you may have that class waived in Med school. What do you think about this? Should I plan to take this class some how and learn some of it before med school? Or is it okay to save this class for med school? I don't know.
