Here is what I think the confusion is.
A. The criteria for " AMCAS Course Type listed below are not included in AMCAS GPA calculations"
is the “Course Type” first has to be pass/fail to begin with. If a course like “physical ed” and it is not a letter grade course, it will be counted as “Supplemental Hours” and it will not be accounted for GPA calculation.
B. If the course is a letter grade course, especially BCMP courses. The Grade conversion table will apply. In OP’s case, Math is a letter grade course, if he gets a “P”, 2.0 will be used for his GPA. In my previous posting, I pointed out the 3rd chart in UG GPA conversion has the “P” grade as 2.0, actually, both 3rd and 4th chart all have that grade references.
