I got my scores back from the December 1st SAT and I received a 1520 (RW 750 and Math 770). Is this worth retaking? The hardest schools I’m looking to apply to are Duke and Hopkins. I am a junior and in the top 5% of my class. Should I just keep my score and focus on my grades and subject test? Also, I did study for a little less than a month in preparation for this SAT. I got -5 Reading, -0 writing, -2 math. Thanks 
No. Great job!
And ECs and essays (although it’s a bit early for essays, you can still start organizing thoughts).
Good luck.
I think it would be a good idea to think the overall image you want to portray on your common app and how your EC’s relate to your passions.
