Can I raise my SAT score to 2000?

<p>I’m a junior in high school now; and last year when I took the PSAT, my score was 160 (about 1600 SAT score). This year I’ll take the SAT in January and another one in April and I’m really nervous about getting a good score. My family couldn’t afford prep class so I self prep. I would say my weakness is vocab and reading comprehension (due to the fact I only lived in the US for over 4.5 years). I really want to attend UC Berkley or UCLA with computer engineering as major. How do I increase my SAT score and what are my chances of getting in these two school?
P.s: I’m a really active member in both Key Club and CSF. I’m also in tennis since my freshman year. I constantly keep my GPA 4.0 (freshman to sophomore year, except for last semester of sophomore year I have a little hiccup. 3.8), I have 3 AP classes at the moment and I’m trying to aim for a 4.4 GPA or above</p>
