Did I do bad on my PSAT?

You got a 1550 on your PSAT, I advice you to take some SAT prep. cles which will help you prepare for your test. If over 1800 you're looking at very good colleges such as NYU. Try to keep up your GPA up, get it as close to 4.0 for better chances, colleges these days are very competitive these days. Keep your resume sharp and stay out of trouble!
