How to get a good score on SAT

<p>Hey everyone! I'm a sophomore, and I have to take the PSAT this year in fall. I was wondering how early I should start studying? I really want to qualify for the NMSQT. I've heard that people have started studying 2 months before the test and aced it, but if it was that easy then wouldn't everyone be acing it? So I just wanted to know if I should start now. Also, how do I study for the vocabulary section? I was going to just start memorizing words in alphabetical order, but is there another way? Please give me tips. Thanks!</p>
