An exchange!

[Lovecom44]

Hi!
I'm currently in my first year of high school (grade 10) and I plan on going on an exchange next year (grade 11).
I was wondering if anyone has any advice. Anything would be helpful. Like how to prepare, what it's going to be like, etc.
My school doesn't have a Japanese class, but it does have a Japanese club, so I'm currently learning Japanese online and through books.


Thanks in advance!
