Take tests early for the best outcomes

If you choose to submit SAT or ACT scores to College of San Mateo, aim for your first test by the spring of junior year, then use the summer before senior year and the fall for retakes. Because College of San Mateo does not offer Early Decision, work backward from its regular application deadline and choose the last fall retake only if those scores will arrive in time.
