The TA graded the at-home version of the exam. Pending my inspection of the grading, here are the statistics 23 people took it Graduate average was 49.25 and stdeve 3.8 (as against 38.7/11.7 on the in class one) UG average is 33.3/6.64 (as against 25.3/14.3 before) There were six inversions--where people did worse on the at-home version than the in-class version!
