Common Application: Volunteering

<p>I've been volunteering at this hospital since the end of 11th grade and I was wondering what I should put for the "time spent" part of the application.
I plan on volunteering for a year so should i put 1 year or even more (at least 1 year) or just like the 6 months i have done so far? So yeah, I am pretty confused about this part.</p>
