My freshman year of high school, I scored a 1090/1600 on the PSAT. I am currently a sophomore and retook the PSAT receiving a 1250 without doing any studying for the PSAT since the previous year. I scored a 690 Reading and a 560 math and rank in the 95th percentile nationally. However, 1250 is no where near my goal score and I need about 300 more points to be happy with this score. Is this possible? Are things like Khan Academy and free online material sufficient, or should I purchase a program like Prepscholar or Kaplan? How much time should I be spending on SAT prep per month? Per week? Per day? I am finishing my sophomore year currently so I do have some time before my official SAT, but I still have to worry about upcoming things like National Merit Scholarships etc. Thank you!
