Back in high school, summer was a time for a break, when we could hang out with our friends. all that changed when we started college. It becomes a time to take on even more work, and our buddies are scattered throughout the country. Here's how to get the most out of your work when the days are long and the nights are hot.
If you are like most students, you will either get a job, or take classes. Both are good ideas. If you take classes, take the ones that you think will require the most work. You won't be distracted by friends or organizations, and you can put in more time than you would during the fall or spring since you won't have to worry about so many other classes.
As for a job, make sure its something that will help you with your career and think resume building. See if you can get a job or internship with a company you would like to work with after college.
Just because something doesn't pay doesn't mean you can't get a lot out of it. Look into volunteering or an unpaid internship if you cannot find a paid one. It will help you develop needed skills and you may find useful networking opportunities.
Also consider taking the time to research. If you will be graduating next year, see if you can visit the graduate school you would like to attend or a city you are considering living in.
