Don’t worry!! You can do this, I didn’t mean to scare you 🙂
I think yes, if you’re doing a brief overview and mainly discussing the topics, it is doable. The labs can be found on youtube also. Not saying youtube is better, just saying it can be another tool to help.
From what I remember, the formulas are easy to figure out, and I think I did let my daughter use her formulas on any tests that she took. Also check out Khans. We used it a couple times to explain things more thoroughly and it’s free.
And saying all that in my other post, I should have explained my child. She does not care about anything other than literature readings. She has an “I don’t care” attitude with math and science. So for us, it was difficult. Others breeze right through it. I also spoiled my kids by holding their hands when young, so now they expect me to help them with everything and I’m trying to cut the cord, a little anyways.
And to be completely honest, I didn’t remember anything from physical science while in college, and completed chemistry and physics with no problems.
Just take the chapters slow and you’ll be fine
