<p>What if you said you were going to take a certain AP test (since you are taking the class) on your application in the fall of your senior year, but by the time May rolls around, you don't feel ready? Would it be OK to not take the AP test anymore?</p>
<p>Sure, as long as you remained enrolled in the class.</p>
<p>Taking the class isn't like signing a contract saying you'll take the test. There's no dishonesty in not taking an exam, especially if you don't feel that it will be worthwhile. Besides, the colleges don't even get your AP scores unless you send them. I doubt they care much, if at all.</p>
