I got my PSAT Score today and I have a question?

I got a 177 out of 240 and didn't study or anything. I'm a junior and I've only taken the PSAT once. I didn't take it my sopre year. I got a 70 on the math and a 56 and 51 on the other stuff.I'm taking the SAT in January and June. I'd like to get a 2000+ on the SAT but I don't know if I'll be able to improve that much in about 1-2 months time. I've never taken the SAT before. I have to review books for the SAT. ( Kaplan and Princeton Review). Also, i'm currently in an SAT verbal and math prep cl in my high school. Do you think I will be able to improve my scores in the critical reading and writing section? I'm really good at math so I'm not really worried about that section. I'd like to attend University of Pennsylvania in 2010 so what score should I be aiming for? DO I even have a chance?
