<p>I’ve prepared for both the AP and SAT Chem Tests, and the material is significantly different. Chemistry is my best subject this year, and I plan on making a 5 on the AP exam. My teacher is good, the course is rigorous, and everything seems to be in order, but when I take practice questions for the SAT Subject test, I have no idea what to do and I get rarely above 70% correct. From other takes of both these tests, under the same teacher, Most people get 5s or occasionally 4s on AP and something rarely above a 650 on the SAT Subject test. Colleges that I’ve talked to said that most anything above a 700 (Rice/Vanderbilt/Cornell), 720 (Dartmouth, Brown, Northwestern), or a 750 (Harvard, Stanford, Columbia, U Chicago, Yale) is what they want to see and will very likely accept. I currently am also in AP Physics, which is more challenging for me than AP Chem, yet when taking Practice tests for SAT Physics, I rarely get less than a 90%, and the teacher for that class is known to have low AP exams. Same goes for AP US History/SAT US History. I think it’s mainly up to the individual, but food for thought. I shan’t be taking the SAT Chemistry test, I plan on majoring something more Math/World History necessary. But good luck on your tests!</p>
