Take tests early for the best outcomes

If you choose to submit scores to Caltech, take your first SAT or ACT by the spring of junior year and reserve the summer before senior year and fall of senior year for retakes. For the November 1 Early Action deadline, October is typically the last retake that can arrive in time, so use earlier retakes to build a stronger superscore.
