The term 1.25*(Q1+Q2+Q3+Q4) scales your total for the first four questions to 100. To be fair to the few students who worked Q5 with some success, the Q5 score is added as extra points. The original and the modified scores will be posted on BB. **) The posted histogram is based on the original scores. **) Average and standard deviation for Test#3Mod: 66.5% and 22.0%.
