The time commitments vary from chapter to chapter.  During their first semester, new members attend a variety of activities to meet other chapter members, learn about the organization's history and values, and develop leadership skills.  Each chapter has a weekly chapter meeting, fundraising events, community service projects, educational programs, and other events that members are expected to attend.  These events are planned in advance to allow members time for studying, involvement in other organizations, work, and other activities.  Time spent at chapter events ensures he or she is getting the most out of the organization.
