Does anyone know of a good, free online homeschool that works at your own pace?

im in 8th grade and want to p a grade ahead so i graduate before im 18, i go to connections academy and they give me extra cles that i dont see myself using in the future...for those of you that attend or have a child that goes here, can i email my homeroom teacher to ask them to take those cles out or do i have to just spend 200$ on the software i need for it? and what about the star tests and big things like that? if i work ahead dont i still have to wait to take that? just tell me if i can just keep working till i get to the end of 8th grade and move on to 9th...i really really need to graduate before im 18. thanks
