I had also bought Physics, but ds decided to just take it at community college. I think it would have been OK with videos and if I could have gotten him to be more organized. We have considered Biology for DD (It looks good), but she is going back to PS next year. The Geo, went well for DS. Just info you have to know and lots of fill in the blanks. I liked that he covered the material without me. dd has used 1/2 of the music and has on several occasions commented that she knew something about music and when I asked her where she learned it she always answers, "In those Pace books." Both children have used the Health books to cover health. I would suggest Alpha and Omega for Literature.
