Are the ap exams and subject tests comparable

<p>I next year I am planning on taking ap chemistry and also the sat II chemistry test. I am planning on taking them at around the same time so my main question is, if I study and work hard for the ap exam how much additional studying would be necessary to get a 780+ score on the subject test?</p>

<p>I think they’re pretty comparable. I took the AP US test last year and then the SAT II US History the same weekend without any additional studying and did well. Although I can’t speak for chemistry…</p>

<p>the AP chem exam is harder and covers more than the SAT II. I got a 750 on the SAT II after taking honors chem</p>
