How difficult is the AP statistics exam without taking the course but studying through prep books. Same thing for AP environmental science?
AP Environmental is one of the softest AP’s, extremely easy to self study if you can set aside enough time to get through a review book or two. AP Stats… depends on the person and their level of understanding. Our school is only having around 30% of students taking the class take the actual exam because they don’t feel prepared enough, while I know friends who self-studied over the summer, reviewed a week before, and got a 5. Really depends on you and how much effort you can put in, as well as your additional activities/courseload.
