In high school, I also took GT Physics followed by AP Physics and the difference was the math and the frequency/sophistication of lab experiments. There are now several combinations of choices for Physics alone. There are also more choices beyond the traditional Biology, Chemistry, and Physics trio. As for Calculus, I am realizing that it may partly be an issue of the breadth and depth of coverage as well.
Well, an almost quote from on the vice principals of DS's High School. 'Don't worry your kids will get a chance to take AP science courses, we now offer AP Environmental Science Course and it has no prerequisites beyond passing the basic required science sequence. (earth science & biology)' While I have no problems with AP Environmental Science and it sounds like a great class, it seems there is less and less emphasis is getting most kids to take Chemistry and Physics.
