I have a few questions about science for this upcoming year. I plan on using Rev to Rev with my 9th dd and my 7th ds. I think I have read every post on using HOD for high school

Also, I had planned on doing physical science in 8th grade with my ds next year. Then we would continue to do high school level science in his 9th -12th grade years. But physical science is the focus for Rev to Rev this year. He is in 7th this year. So if we do physical science in 7th it seems to throw things off with science. I know we could use the advanced log but he is 12. We would not want to use the 9th-12th grade years to do physical science again because many colleges are not counting this as a science but as an elective. Next year chemistry is the focus for science in M to M. I am trying to figure this out. Any help will be appreciated

We have used LHTH, LHFHG, CTC, R to R and Rev to Rev this year!
Blessings,
Taryn
