Technically, you are still a youth.
Chances are, you will not be assigned to,
or paired with youth, but with children.
And tuition earns money, so unless you have the qualifications
and joins a legitimate volunteer organisation like the church,
temple, CDAC, Shihk associations or work with the mosque.....to
provide tuition.
You are better off just volunteering your services with other
youth groups (To be with other youths.)
And unless you did tried to get some group skills with CDAC and
the CC's youth group, you dont have any experience that will
ecnourage other volunteer group to take you on.
Volunteering, though comes with the goodness of the heart, but
without discipline and group skills, still is a loose cannon for
the Volunteers Organisations.
