This is my personal take. Anyone who games the system by taking easy classes simply to get into Cal Poly will have a tough time getting out of Cal Poly. I also think those students are rare. By far and away the biggest rigor bump in the MCA is taking math through at least calculus AB. That alone accounts for 10% of the total score. How many students take Calculus, but skate through by taking the easy route in all the rest of their classes? How many students that take the easiest route do extremely well in their standardized testing? Yes, GPA is the king, probably rightfully, but it’s very easy to see how attempting to rig the system might not actually benefit the student.
