American school of Correspondence Geometry?

Ok, I only have two courses left (one being geometry) and I'm planning to go to a vocational school for surgical tech but cant enroll until i finish high school and the deadline for the class is at the end of the year so i want to finish before then. my only problem... geometry is IMPOSSIBLE!! in school i was good at it and had no trouble but in this book im so confused and am finding it hard to get even the first one done. So with no teacher and no one in my family that can help i though maybe id try posting a question ^_^ is there any who has done this subject or is currently doing it? id be happy to help with any other course you may have that I've done . we could help each other >_<
