Lv 5 Difficulty Math Problems

<p>Hey, i am currently studying to take the SATs at the end of my sophomore year. I had a score of 74 on the math portion of the PSAT, however i set a goal to get at least 790 on the SAT MATH. I sometimes have trouble with the last 2 questions, so can some of you guys post some questions that u tought were hard/difficult on the past SATs?</p>
