<p>Hey, im taking the SAT Subject Tests in Chemistry and World History tomorrow. I did not study at all for the Chem one and prepared for the world history one last month with the WHAP exam. If i dont want to take the chemistry exam (because i am totally unprepared), what do i do? Also can i replace it with another exam at no extra cost? I did pretty good on my Biology SAT last year so its no problem if i dont take the chem one. Thanks!</p>
<p>When you get to the test, you can choose which subject tests you want to take. You can drop the Chemistry one and just take World History, or you can replace Chemistry with another test. I don’t believe you even have to notify anyone that you’re doing this; all of the tests come in one booklet.</p>
