<p>I disagree with @DrSteve with regards to testing. The SAT is very methodical and you need to try to take the exam as much as possible in one sitting to try to replicate the real test. My d took the exam once a week for the 10 weeks prior to the exam. She brought her SAT score up by about by a little more than 400 points by doing that, and 45 minutes of prep per week.</p>
