This is my second year home-schooling my high-schooler. My first year I used the Life Pac curriculum for all 4 courses. This year I am using Life Pac for the History and Language only. I am using the Apologia Science Series for Biology. I'm still looking for a Geometry course. The Life Pac Alg. 1 didn't have enough instruction. (It was good, just not good enough.) I try to use pre-packaged courses because I work and the math is beyond what I learned. Using different curriculum seems to work better for us.
