MZ Beattie is sadly mistaken. If you miss a curve and wrap your pickuop around a tree, with mortal consequences, it is NOT because you were "going to make the curve later".

Failing might well make a student less enthusiastic, and getting great grades makes him feel more enthusiastic. If it all just amounts to succeeding anyway, and failing equals succeeding deferred, then there should be no test. The teachers should not use them, because they will succeed sooner or later, so why bother?
