I think that students benefit from going to school in another country for a term or even a year by learning another language and making a lot of new friends.
They also have the possibility to see new places and to learn the costumes of a completely different culture.
In addition, studying abroad can help you to make decisions for your future studies and life, and it helps a lot to become independent, because you're in a new country without your family.
The first picture shows the problems that you can have by eating the food of another country, while the second one shows that is difficult to make new friends if you don't know anyone and furthermore you come from another country.
Picture number three makes me understand that If you don't know the people and the language , you can feel a bit uncomfortable by hearing the others talking to each other.
The last picture shows that you can find difficulties in following the lessons, if you don't know the language perfectly.
If I were at school in another country, I would try to eat its typical food, then I would try to introduce myself to the other people and make new friends.
Also, I would try to have a conversation with them, even if I didn't understand every word, and lastly, I would ask the teacher to speak a bit slowly at least for the first month, and to be patient with me if I didn't understand.
