If you qualify to study abroad while at UC Berkeley, I would highly recommend it. It is going to be an experience that you may not have the opportunity to take again in your lifetime. Check out your options and decide where will be best for you to study. You can experience the outbacks of Austrailia, the culture of France, the diversity of China..the list goes on and on. Just imagine waking up in another country, going to your classes, taking the bus with the locals. See how the children in that country learn and relate to you. Don't let the fear of not knowing what to expect hold you back. Take a leap and have a great experience while getting your college credits.
Why not expand your horizons?
