High School Math Help?

i have never been good in math. and in 9th grade i will be taking Algebra 1. and i was wondering what we will be learning in algebra 1 so that i could get kind of a head start and kind of learn ahead of time to help me be prepared for next year. so if you could give me kind of what we do, and if possible, in order. if that makes since. like, do we learn in order of the chapters in a math book? i just want to get some of the concepts and procedures down, so i can study them and do problems. thank you so much! and if you have any extra info on algebra 1 or tips i would greatly appreciate it!:)
