For classroom courses, you need to be enrolled in a program that began on or after February 20, 2005, attend your classes (or their makeups), take all of your scheduled tests during the term of the course, and complete your homework. If your score isnt higher on the actual exam than your earlier, official test score (or first proctored diagnostic test if youre a first-timer), then you can work with us again at no charge for up to one year, or you may get a full refund. To be eligible for the refund, you must take the actual test within one month after completion of your course and present a copy of your official score report and your diagnostic score results at the time you invoke the guarantee (no later than 90 days after your final course session). Refunds may take up to six weeks to be processed. You can keep your materials...were not that cheap.
