Unless you have many other hours of non-clinical volunteering to list, that is your best choice. If you have that category covered, pick Teaching, as voluntary mentoring falls into that category, too. This would not be leadership unless you are in charge if other BBBS volunteers.
Awesome, thanks! Hopefully not too big of a hassle, but one more question. Should I list research that was done during a class (ex: cell biology) that was a regular science prereq with lecture and lab? The research consisted of finding our own independent topic that could be experimented and then testing our hypothesis and creating a poster to present at our campus research symposium.
You may list the research, even though you got class credit for it. The poster can be mentioned in the same space.
