Retake SAT with 1550 for competitive colleges?

Asian Junior, 1st seating Sat score is 1550 (760 RW + 790 M) from November test in 2016. Other aspects of academics are strong so far. Aim for very competitive colleges. Is that worthy to retake Sat to improve 20 to 30 points? Looking for your advice. Thanks.

No, probably not. This article has more details about why, but basically once you've scored above a 1530, any score increases won't dramatically improve your chances of admission; it's better to focus on other parts of your application (like your personal statement).
