Will retaking SAT Chemistry make a difference at this point?

I recently was deferred by my two EA schools Caltech and MIT. SAT 2300, M2 800, Chemistry 710, UW GPA 3.93, W GPA 4.8. Good EC. Great essays. California resident. Computer science and engineering major.

I also applied to USC, Rice, Cornell, Columbia, UCs, Stanford and Princeton. I got into Santa Clara University EA.

I think this 710 is the weakest point of my application. Should I retake it or it is too late to make a difference?

It is possible that it could help. It probably depends on how Quickly you can get the result.

It may also help if you are wait-listed somewhere.

Thank you @Much2learn . it just seems that majority of those schools to not take January results.

In that case, it could only help with a wait list situation.

For those two schools it probably made a difference but No. A 710 is a good score. That will not be a difference at other schools.
