Need help in improving my SAT scores in short amount of time

<p>I am currently a junior in high school and I am about to take PSAT and SAT soon and I am devastated here. I took a SAT prep course and it increases my score significantly from 1230 to 1650; however, it never goes higher than 1650 but continue to linger around 1570~1600. I studied all the books my dad had purchased for me for a year and my scores never seems to get higher. Among all the scores, math and writing are equivalent in their scores while reading is significantly lower (English is not my mother tongue and I have memorize 1000 most common SAT words, but passage-based questions bore me even though I tried so hard to underline, make notes to help me stay focus.) I really want to enroll into UCLA… please help. Thank you.</p>
