ED1 or ED2 please give me advice

Hello
I receive my SAT score today, but my score is poorly low.
I have a 2020 on my latest score. I feel kind of depressed.
Can anybody tell me what should I do to increase my chance of getting into Tufts?
If I take SAT again on December (I have SAT2 on October) , will it help?
Can anyone give me at least some advice? I sincerely ask you for help.

The ONLY difference between ED1 and ED2 is the deadline. It’s still a binding decision, so the admissions officers don’t care too much if it was your first, or possibly second choice. If you think you can do much better on the December SAT, go for it. Just know it means you have to apply to all of your other schools, since you won’t hear back from Tufts until February.

It may sound a little cliche, but the most useful thing you can do at this point is write some fantastic essays. The Tufts prompts are much more about you than your academic interests, so express yourself!

I was an ED2 admit from last year, so all of this is from my experience.
