text: This test consisted of 85 questions. The first 23 questions numbered 1-23 were classification questions. The next 15 questions, numbered 101-115, were called relationship analysis questions. The SAT Subject Test in Chemistry was currently the only SAT that incorporates the relationship analysis questions. Relationship Analysis Questions required the student to identify the truth value of two statements. If both statements were true, the student would then have to analyze the relationship between the two statements to see if the second statement correctly explained the first statement. The last 47 questions numbered 24-70 were standard multiple choice questions. The metric system of measurement was used, rather than United States customary units. This was widely because students across the world would take SAT Subject Tests, not just Americans. Additionally, many chemists and scientists use the Metric System, considering the entire world uses it as well.
