Questions that less than half the class answered correctly: 6, 11, 12, 13, 21, 26, 27, 28, 32, 35, 39, 40, 42, 43, 45, 48, 49, 50, 51, 52, 53, 54
Questions that less than one-fourth of the class answered correctly: 6, 13, 47

All questions, including the extra credit, counted as two percentage points, and bubbling in your name correctly was worth one percentage point.  So the highest score possible (pre-adjustment) would have been 109%.
Class average (pre-adjustment):  60.3%

That average is so low that an adjustment is called for. The average on the second exam was 73%, which is a lot more like it. So, I am multiplying everyone's score by 1.21 (the technical term for this is a scalar adjustment), so that we get:
Class average (post-adjustment): 73%

High score:  119.8%
 

Grade	Score (post-adjustment)	Number of students
A	90-100+%	[to be entered later]
B	80-89%
C	65-79%
D	50-64%
E	0-49%
