<p>As MeIsHM notes, first start by taking a full practice test, to see how you process it. For able students (as you obviously are) the challenge is often learning how to take the test, vs the content. The SAT tests a certain kind of thinking as much as anything, and some people ‘get it’ innately, while others (just as smart) don’t. The maths is not advanced- in fact you may have to reach back a few years to more basic algebra and geometry- but the phrasing of the questions, and the answers offered are deliberately chosen to mislead the careless. Use your practice test to work out what sections you need to review- a general course may not be your best resource. And yes, a month- especially as you are not tied up in school work right now- should be plenty.</p>
