5	8.1	(1.7)		107.5 ^f	(47.6)

The Rubric score is on a scale from 1 to 10 with higher grades indicating better performance.

The time to complete suture is measured in seconds.

^ap = 0.007 when compared to 1st year students.

^bp = 0.004 when compared to 1st year students.

^cp = 0.002 when compared to 1st year students.

^dp < 0.001 when compared to 1st year students.

^ep = 0.03 when compared to 1st year students.

f. p = 0.027 when compared to 1st year students.
