<p>This is so retarded. I will go one test and get every single sentence completion/vocab question right, then I will take the next one and get 4-5 wrong. Why can't I ever get the former on a real SAT test?</p>
<p>Well, it's pretty much random which SAT words show up on any given test. The idea is the more words you learn the more words you'll likely know on your actual test. While there's no guarantee you'll ever have a test where you know every word, if you keep learning new vocabulary (especially the ones you get wrong on your practice tests) you'll increase your chances.</p>
<p>hmmm
may I suggest trying ACT?
vocab was my weak point as well so I tried taking the ACT and managed to score better =/</p>
