I think that this last statement is the key. My job is to help my INDIVIDUAL students do well, and probability is no guarantee for EACH student. If s/he is an UNlucky guesser, an otherwise good score that represents a year's worth of work could be severely damaged. If all my students guess on every question on which they cannot get down to ONE answer, the group's grades should benefit, but in my mind it's not a group test and my concern for each individual student says it is not worth the risk. > >Chris Harrow >Mathematics Department >The Westminster Schools >1424 W Paces Ferry Road NW >Atlanta, GA 30327 >firstname.lastname@example.org
