Does it matter how your volunteer and shadowing hours are spaced out? For shadowing I was able to put in ~40 hours over a two week span (will work on more), for hospital volunteering I go during summer and winter breaks, and for nonclinical I have volunteered as a camp counselor at a sleep away camp for a week which was also many hours. Do I necessarily need more long-term hours for the shadowing and nonclinical?
