One of the smartest people I know did 4 degrees in 4.5 years: undergrads in physics, chem, biochem, and math. He graduated with like a 3.2 gpa, low because he took 18-22 credits of hard classes every single semester, and couldn't get into med school. They made him take some stupid biochem masters, at which he excelled, particularly with a reduced course load. He then easily got admitted to med school.

If you don't want people to prioritize grades over everything else...
