In these pages, we will focus on the one-month exchanges we set up between our schools in Réunion (St Exupéry) and in Oulu, Finland (Laanila and Svenska). Nothing was easy, we had to juggle with the many restrictions and ever-changing health situation... Nevertheless, we managed to welcome 4 students from Laanila High School in Réunion for one month (November 2021), and sent 6 back to Oulu in Décember, 4 students on exchange with Laanila, and 2 with Svenska.
