I remember something similar on the LSAT. Odious practice; if you get a wicked problem in a professional context, you don't have the option of just blowing it off. Of course, you could say it's about learning to prioritize with limited resources, but that's meta-gaming the applicants and selecting for corner-cutters. There's a place for corner cutting; in emergency situations it's sometimes the right thing to do. The problem is that selecting for corner cutters also incentivizes exploiting the system for less noble motives.
