Hour/Week Woes with Common App

Trying to figure out how to talk about tutoring on the common app. Sophomore year I tutored for 5 hours a week, 18 weeks. Junior year I tutored 3.5 hours a week, 18 weeks. Should I list them separately? Or find the average of the two?

Probably inconsequential, but help would be appreciated.

In the grand scheme of things, yup. Just average them. Nobody will audit your hours as long as they are in the realm of possibility. If all your EC’s total 80 hours a week, for instance, expect to be challenged. 4 hours vs. 4.25 hours - no issue.
