29 exams were submitted and scores ranged from 42% to 98%.
The mean score was 70.69%.

As a result, I curved the scores, raising each score +5 points.
The scores then ranged from 47% to 103% and the mean score was 75.69%.

The numerical score will correspond to a letter grade as follows:
 

Grade	Percentages	# Receiving
A	90-100%	8
B	80-89%	1
C	70-79%	9
D	60-69%	6
F	<60%	5
