Is it possible to study abroad during the summer?

Yes. There are programs for international exchange students, for summer. There are websites for this however I am not sure the one I would direct you to. You may want to ask Jared, he many know about the sites for this. I do not want to send you to the wrong place. However, I do know depending on what college you are attending and others that offer the home to you in summer for summer camp and summer studies. You would most check with the college you are going to attend first. Google or Bing or whatever you use to search for what country, subject etc. you may want to study see what is offered in summer school. However, I think you would want to arrange this several months prior to going so you can plan this trip properly as well as check all references making sure you will be safe where ever you decide to go to for your studies. We sometimes have travel warnings for certain countries that our government issues for safety purposes. Right now this is the Ukraine as well as Iraq in some areas. So it is always good to check on that as well for the safety of you and the other party. I found two sites you may want to look at. National Geographic, the other one is People to People. This also depends on age, grade and length of stay etc. So much research must be conclusive.
