This depends on what test you are referring to. \r\n\r\nI studie about 2+ months for the SAT I\'s, about a month of so for my SAT I math. \r\n\r\nFor my AP tests--I studied alongside the courses was taking at school (but I started reviewing old material m ybe a 3 months before taking the test and really cracked down n my studying a month before). I began reviewing so far in adv nce because I would usually take more than 3 ap\'s a year. \r\n\r\n guess you can see what study plans work out for you. I\'m not of slow and steady learner than a last-minute crammer. It\'s a l t less stressful, in my opinion.
