There are many ways to work it out so you can study and intern abroad at the same time. The important thing to remember is that it can be done - sometimes all you need to do is ask for what you want. Be flexible, and don't be afraid to ask for a little flexibility in return, whether that means changes to your class schedule or slightly-odd internship hours. As long as you do your best at both efforts, others will be impressed by your ambition, and you're guaranteed to have a rewarding and productive time abroad.
