SAT Chemistry overview


SAT subject test in Chemistry is administered by College Board.

Time: The test is 60 minutes long

Number of questions: 85 multiple choice questions

Calculator: Not Allowed

Periodic table that indicated atomic numbers and masses is provided on the test.

Test Dates: Test is offered in August, October, November, December, May, and June.
