How can I find 10th grade curriculum before 10th grade begens?

Hi(: I have some learning issues including dyslexia and ADHD. However, even with my disabilities I am determined to do well in school. I like to study for the upcoming year the summer before so I can be ready and keep up with the other kids. I don't have much parental support on this so I'm kinda on my own. Anyone know how I can find out what the 10th grade curriculum is online or threw books? Thank you so much for your help. 10 points to best answer!
