Thank you Gwen - I can see I have more homework to do...It is very useful to know how the math fits in...Since my son is entering 9th, I'm figuring out what he needs in 12th and working backwards... If yours did calculus in 11th grade, did they do the AP calc in 11th grade also? or do another year of prep in 12th grade? Mine just finished Algebra I in 8th gr and so I'm trying to figure out the math too, since I've read that Saxon geometry (included in the other books) is weaker than whole programs...could I ask your conclusions on the math path? and then whatever happened to trig? I occasionally see it appear. Has it taken a back seat to Calculus? Thanks, Joan

To those who have travelled the science path... I am wondering if my son should do a high school physics course in 11th grade before he does the AP physics course in 12th grade? To get into university here in Switzerland, he has to have done 5 AP courses and since he is scientifically inclined, the physics should be one of them... Thank you!
