My honors chem class was in 10th grade. It barely touched on electronegativity, nor acid/base chemistry in a through way.
To expect a student to pull that experience forward two years later and integrate it with calculus to pull off organic chemistry seems non-ideal for many students.
And you really need the through physics/calculus component unless you want to wave biochem students past thermodynamics, which seems crazy to this former biochem student.
Cut the one quarter quantum mechanics class, perhaps.
There is a competing college credit test system, International Baccalaureate, that actually includes lab work as part of the test.
Physics and calculus are available too. The right ones would be AP Calculus BC, AP Physics C Mechanics, and AP Physics C E+M.
These are good students, so they enter college with AP Chemistry and AP Biology credit. Start off college with Organic Chemistry 1, then Organic Chemistry 2, then Biochemistry. That's just 1 year to take the classes actually needed to enter medical school in the USA.
Some students might even take those classes via dual enrollment (a.k.a. dual credit, early college, etc.) while still in high school.
That is 0 to 1 years needed after high school. The medical schools demand a 3-year degree (actual time) at minimum, which in the USA means a 4-year degree. Subtract as you please, and you'll get an unjustified excess of 2 to 4 years.
