We are a class of IBY1 students. The idea is to spend a week in a ib school from another country and meet other ib students. Then, these students would come to our high school in Spain (a city near Barcelona and Zaragoza)
At my school (in Spain) we've been doing an exchange with an IB school from Australia for a few years and it is a really awesome experience! So if you have the chance to organize something like this, i would totally recommend it!
