|If you're going to a new school, that might be a bit scary.
You should ask your mom to take you the very day before school to know what it looks like, and meet your knew shool teacher.
At least a week before school you should probaly stock up the school supplies you need, such as pencils, pens, and notebook paper. These will probably all do you some good.
If you've been home-schooled your whole life and it's your first time going to a new school, then my advice is that you should probaly get an American Girl book called School Smarts. That should definitely last you through the whole school day.
If you can't find the School Smarts book or other school books available at your book stores, then you should just probably stay cool, be nice to everyone, and do your best. If you meet someone that's been to your school before, then you could ask them advice to help you get through the day.
