You have 3.2 seconds to figure out the problem below. Alan knows 90% of the concepts behind the math test, and can do those 90% very quickly. He always gets 90% on timed math tests. Bob knows 100% of the concepts, but is a slow worker. In the timed math test, he gets 75%, but, if given an extra 10 minutes, would get 100%. Alan graduates with an A; Bob with a C. You are building a bridge. Who would you hire? Seems like everyone from Gates to Zuckerberg has problems with how education is carried out today. I wish I had some of their clout and could help to change the system.
