AP science is not a single course but 3 separate courses. Students can take 1 or all 3. Each of these courses offers a more in depth look at the subject material than the regular version of the class and as a result each of the courses requires 2 classes to cover the material. Students wishing to take any of these must start taking prerequisite classes for the course in grade 10. Each of the courses has an increased lab proponent, and better prepares students who intend to do science related university degrees.
