Hi! Wow, clearly you’ve worked hard. Congratulations! I’m not an an admissions office, but if I were, I’d be suspicious of how you were able to achieve straight A’s from the start of HS, despite (in your words) your English “really suck[ing]”, and within two years scoring a 1530 on the SAT as a sophomore. If all I saw were your grades and SAT score, the assumption would be that you were fluent before you came here. Thus, to me, I think an essay on being a second language learner would be appropriate, especially if you were able to address struggles in earning these achievements. Try to get into the heads of the people who are going to review your packet. Good luck!
