EA Harvard or Northeastern?

Hey guys, currently a super stressed out High School senior and I just realized that I cannot apply REA to Harvard and EA to Northeastern. I am currently torn on what to do.
I do not have an SAT OR an ACT score (I could not take it due to COVID cancellations), which I know makes my chances of getting into either much lower.
So, I don’t expect to be some ‘shoe-in’ for Harvard or Northeastern. My GPA is good, and I take rigorous courses, and both are kind of a shot in the dark.
What should I do? Is it worth it to do REA Harvard, even though my chances are slim both ways? Does EA at Northeastern greatly increase my chances? Thanks!
