I thank @APH-Nordics (sorry for mix up guys) for the request and I think we all feel ya when you have to adjust to a new school. It hard and sometimes it sucks because it's not what you're used to or you don't know anyone. Photo doesn't relate to anything it just funny.
1) when adjusting to a new school you should always figure out which teachers accept late work because that's always important when you have a lot of homework
2) try and join clubs if there are clubs at your school because it helps you interact with other people and you can learn important life skills
3) be yourself because you shouldn't have to change you when at a new school
4) try and make friends because even though you might not like human interaction it will help you because they will be there to help you if you need help
5) if your failing a class ask the teacher what you can do to improve your grades, don't be shy to go to tutoring because it will help you
6) try not to be a loner because it will make it seem like you don't want to have anything to do with people and that isn't always a good thing when ever you have to do partner work
7) if it's still really hard to adjust try talking to the school guidance counselor or your parent(s) about how they adjusted to new schools and what things can you do to adjust
