Improving in SAT!

<p>I'm going into my junior year and have to take the SAT's very soon and I'm freaking out! I only got a 157 on the PSAT's..that's ridiculously low! I got around 55 in CR, 62 in Math and only 40 in writing! Do you think I can bring up my score a considerable amount? I really want at least above 2000 on the SATs but realistically how much do you think I can improve?</p>
