What do I write?
You write the hours you've volunteered. Say for instance, you volunteer from 1-4 pm that means you write that you volunteered for three hours that day.
It means "estimated hours" - estimate how many hours you volunteered in the community.
The number of hours each day you could make yourself available. So write, for example, '6 hrs each day' or what ever period suits you.
how many hours you want to volunteer.
I have no idea
