Schweser answers

I took the first Schweser practice exam this weekend, and some of the “for the exam” answers seem insanely brief. Are those really acceptable? For instance, their suggested answer for Risk Tolerance will be: Ability: Above-average Willingness: Average Overall: Average Is that really all you need to earn full credit?

I would write a bit more but schweser claims that you will get full credit if you just write these answers. Either is good but more is better
