The tendency, when teaching a course that culminates in a test not written by the instructor, is for the instructor to fashion the curriculum around the test.
I have observed that my child’s exams in such courses have the same format as a standardized tests (state or regents). I feel that it discourages real thought and deep understanding of a subject, and certainly curbs intellectual curiosity, because the intensive time management needed allows no deviation from the syllabus.
I want my child to be able to think, understand, make connections, and come to her own conclusions. Life for most of us is not a standardized test.
Furthermore, depending on where you are applying and what you end up majoring in, the AP exam scores just may not be worth college credit.
