I recently took the SAT Subject Test for chemistry and math level 2, and scored 800 on both. Should I plan on taking a third subject test? If so, which subject would you recommend? I am a sophomore currently, and next year I will be taking AP Biology, AP Lang, and I’m taking honors american history over the summer, so I would take either the SAT biology, literature, or US history if I were to do a third test. I’m not sure how much preparation I would need for these tests. I did not prepare a lot for chemistry, and taking math was a last minute decision, so I was very surprised at scoring 800s on both. However, math and chem are probably my two strongest subjects, and I would most likely need to prep a bit more if I were to take a third one. Is it worth it?
