text: Like most of the SAT Subject Tests, the Chemistry SAT Test was relatively difficult. It tested a very wide breadth of content and expected students to formulate answers in a very short period of time. Many high school students found themselves picking up extra resource material, like prep books and online aids, to help them prepare for the SAT Chemistry test.
  While the test was challenging, there were distinctions between the SAT Chemistry Test and the AP Chemistry exam, which is a more critical-thinking exam that is used not for college admissions but rather for college placement. Still, an AP course in Chemistry is sufficient preparation for the Chemistry SAT.
