What're My Chances ED/RD

I am torn between applying ED to Northwestern or not, because my other school of interest is UC Berkeley, which has a unique application date of Nov.30 with no EA/ED. However, I am not sure of my chances getting in to Northwestern without early decision, as I fall almost exactly at their 50% for scores and GPA, which are as follows:

Math: 710
Grammar/Writing: 720

~4.15 weighted

Intend to apply for chemistry/engineering

I think you have a strong shot in RD too. If Berkeley is your top choice I suggest you apply there by Nov 30th and apply to NU in regular.

Apply RD if you think you might regret not being able to apply to uc berkeley
