Host a dinner or party with your closest friends. Everyone will want to see each other together one last time before graduation. Make everyone's favorite food or have a potluck. Encourage everyone to tell stories from move-in or their 21st birthday. Plan an activity that your group has done in the past, such as laser tag or a bar crawl.
Create a "bucket list" of things you'd like to do before you leave campus. Include eating at local restaurants, galleries to see, hikes to complete, excursions to near by towns, visiting campus landmarks and buying school or college town articles of clothing. Create this list on Facebook and tag your friends. Use the note function to coordinate different outings with friends.
Schedule as few meetings and responsibilities as possible. Be open to spontaneous events with friends, roommates, or professors. Use free time to relax after 4 years of hard work. Hang out in the sunshine in your quad or take a hike in the middle of the day.
Ask your mentors out to coffee. Thank them for their leadership and advice during your college career. Professors and administrators have knowledge about career selection and connections that might be helpful to you also. Tell them what you've learned from them and how you plan to use this information in your career. This is an appropriate time to ask them to be references on your resume.
Go to graduation ceremonies. They provide closure and time to celebrate with your friends, families and professors. Decorate your hat and sit with your friends during commencement proceedings. Go out to a big dinner. Ask your friends if they'd like to do a large group dinner. Potlucks and barbeques are also options for graduation eating.
