<p>Agree with posts on prep courses - they are very expensive with little gain for your dollar, unless you need to be forced to sit down and complete practice tests, but that is usually only one class per week so you, so you are on your own the rest of the week. Money is better spent on a qualified tutor (try your guidance counselor, or even the SAT prep course may have a list of tutors) who will focus in on your weaknesses, provide test strateiges and hopefully help to motivate you!! Practice is the key to success and understanding why you made your errors and working not to repeat them!!</p>
