<p>I think you should retake if you know you can do better. Even if it’s just in one section (you can get a better superscore that way)</p>
<p>2280 is a really good score, but you will be even more competitive if you get 2300+ or 2350+ (which you’re close to! :)) If you can spend some time studying and pull that, then it’ll be a major plus for you. If you have already studied and think you have reached your potential, then don’t worry about retaking. Judging by what you said, you can probably get your score higher.</p>
