Hey, I'm a senior in high school who just finished college apps. I'm taking 8 AP courses currently and so naturally, signed up for all 8 AP exams. I'm extremely stressed about them but I already indicated that I would be taking those exams in my application. Would I be negatively affected in the application process if I cancel some of those exams?

They probably will not care. They will get more money from you in taking more courses. On the other hand, if you don't graduate or have a significantly different GPA from pre-admission then you may find your admission rescinded.

Explanation:

You'll want to have good reasons for missing the tests. Nevertheless, if missing the tests causes you to not pass a required class, then yes, the college would rescind your application or if this causes significant reduction in your grades, the college would considered that, too. If you don’t do what your application said you were going to do, they can rescind your admission. In California, it’s very common for the universities to do that.
