<p>okay guys…i did kinda crappy on my jan 28 exam because it was my first time…kinda choked and didnt know what to expect and was really nervous, but now i feel i can do better. Here my question, generally speaking how difficult are the april tests BASED ON HISTORY OF collegeboard? and another question i want to get 2100+(740 Math, 720 writing,640+CR) bc i want to go to CMU or USC, what are the best books and studying techniques for math, cr, and writing? Ive been doing a crap load of barrons math and english will that be enough? i need a lot last time but was disspointed =(</p>
