The geometry club at the beginning of Fall 2015 completed all of the requirements to be a package 2 organization the previous Spring.  They know they would like to go to a geometry conference in Spring 2016 and looking at the rewards they decide they would like to try to aim for Package 4 so they can get access to a travel budget.  Throughout the Fall 2015 semester they complete all of the requirements for Package 4 and submit their budget for Spring 2016.  Beginning Spring 2016 they are now a Package 4 organization and attend their geometry conference.  Looking forward to Fall 2016, they decide they do not need a travel budget and that the Package 2 benefits are all they will need for the Fall semester.  They complete the Package 2 requirements during Spring 2016 and go back to Package 2 organization during Fall 2016.
