When talking about kcumb you have to remember that we are system based and that there is not a single course that is harder than another one. Every 5-6 weeks you study a different body system and just like at other school, I will say that the neuro section is the most demanding. Anatomy should not be a problem because the only time you go into the anatomy lab it is to study the anatomy related to the section you are studying i.e during the cardio section you only go into the lab to study the heart and during Skin-Blood and Lymph section you do not have anatomy. It is true that once you are in at KCUMB they make sure that you graduate and free tutoring is available (if you had an interview here you heard everything about the ressources available), 2nd years are in OPP lab and anatomy lab or pharmacology lab with the 1st years, there is one office dedicated to make sure that students succeed, etc...In my class, we may have lost 3-4 people for various reasons, but we started at 238. starting with the class of 2009 they are 250, you have to pass step 1, 2 and the clinical skills to graduate. You cannot fail more than 3 sections during the first 2 years and if you fail any you have to retake the exam over the summer.
my main points will be that once you are accepted schools make sure that you eventually graduate and you should not worry about it too much now because wherever you go, it will be up to you to succeed because a lot of things in graduate school consist of self-learning.
