How to improve my score??

Hello everyone! I am currently a Junior in NJ! My school’s curriculum is quite rigorous; one of the top schools in the state. I am in all Honors/AP courses, and maintain a very high GPA. However, my SAT score is horrendous. On the PSAT Sophomore year, I got a depressing 139. CR 45, M 51, W 43. I took the PSAT again Junior year, and my scores did increase to a 157. CR 46, M 62, W 49. I took the SAT in March with little practice, and it was lower than my Junior year PSAT score. I got a 1540. CR 46, M 57, W 51 w/ Essay: 8. I am quite disappointed with my results on the PSAT/SAT so far. I know I can do so much better. I do practice tests in the “blue book” and easily get 60+ in CR, 65+ M, and 60+ W. My goal is to break the 2k mark. I have no idea what to do! I need some advice. My dream schools are UCLA and NYU, and to get into either of these schools you at least need a 2k. Please help me! I need advice! Thank you.
