All your post-secondary grades count in determining your AO and BCPM GPA. You will need to first list all your classes and partition them out as BCPM (biology, chemistry, physics and math) or as "all other" (AO), so you can calculate separate BCPM and AO. Take the letter grade you received for the class and convert it to a number (A=4.0, B=3.0, etc.). Multiple that number with the number of semester credit hours of that course (e.g., 4 credit hours); that's the number of quality points (QP) you earned for that class. For example, let's say you took a biology class with lab that was 4 credit hours, and you received an A (4.0) for that class. So the number of QP you earned for that class would be (4.0 X 4.0 = 16 QP). Do that for all the classes in each category (BCPM and AO). Add up all the QP for the given category and divide by the total number of credit hours in that category, and that's your GPA for that category. Remember all classes count and are averaged, without exception. If you are looking for your total GPA, just average all of your classes in together, regardless of category.
Undergraduate GPA is given more weight than graduate GPA in the medical school admissions process.
