<p>kjcphmom, I agree with everyone who’s posted, your son (S2) should definitely take AP calculus and and AP science, if he is a science/math person. The great majority of students who will be majoring in science/math come in with some calculus experience. The courses are still advantageous even if he chooses to repeat some of the material in college. Many universities offer courses that are tailored to student who have had AP calc/sci in high school, but who are not ready for the upper-level courses right off the bat. These often have fewer students, and sometimes better profs.</p>
