I am moving schools , how hard is it to make new friends?

It's not hard if you take your time to choose who you want as friends. You don't need to rush with this. Take your time. Check who you think that would make you a good friend, and take it from there.

Join a school club or extra curricular activity /interest you have.

Not very in Mt experience.

Just be yourself, you should make friends easily from just being yourself:)

its easy
give a party
