<p>Princeton with a start and Barrons for perfecting yourself. MAKE SURE YOU DO LOOK OVER BARRONS before the exam (and i think barrons have more indepth explanations which is necessary for high score… though its true that it also contains unnecessary things such as rule of sign) </p>
<p>i’ve studied like that , did ALL the practice tests i can get (like, 30 sets? i dunno) and i got 800 , good luck :D</p>
