Pursue Your Interests
Colleges love students who have demonstrated interest in a particular field. Do you have an interest in politics? Campaigns are just heating up. Contact your local candidates and see how you can help. Interested in education? Volunteer at a local camp for kids. Either way you are showing colleges that you have a passion and are committing to growing your knowledge and experience in that area. Volunteering options are numerous and a good opportunity for teens with little to no experience.
Get a Job
Yes, you can always volunteer, but if you need the money, jobs can demonstrate growing responsibility and you will learn the ins and outs of the workforce.
Take a Course
Numerous community colleges, distance learning programs, and your school offer educational offerings in the summer. Not only will you keep your mind fresh, you will also add more grades into your GPA calculation come application season.
Take some time for yourself this summer, but also look at the big picture and find a way to keep engaged doing something you love.
