To arrive at the final MPS, they take all the students who fall between 55 and 65, and then take the midpoint value on a graph. It's called the Hofstee method. From my understanding, the students who scored above 65 or below 55 are not factored into the MPS.

So when they take all the final grades at the end of the semester, once the percentages of each mini have been determined, if the students who fall between 55 and 65 are localized at 57, then the MPS is 57, so you cannot really use the individual minis to determine the final MPS, since they don't take into account what percentage that exam is worth of your final grade.

They explained it at orientation, and had a really good graph, so if you are interested in reading more about it, you can find the powerpoint file from orientation on the gdrive.
