Is my ACT score a deal-breaker?

I have a 4.39 weighted gpa, took AP Calc AB, AP Phys 1, and AP Chem last year as a junior, Currently in AP Calc BC and Multivariable, AP Physics C, AP CS and AP English Lang as a senior.
Straight A/A+s
SAT Math 2: 770
SAT Chem: 790
SAT Phys: 730

And a 27 on the ACT
I’m going to take the SAT in October, been prepping really hard. Can break 2100 in practice tests. But for now…
I’m applying to schools like UCs, CMU, USC, UIUC, U wash, gatech, and Cornell(ED).
FYI Engineering/science major

bump

Have you looked at schools that are test optional? Your stats look like test optional schools might work well for you.

How many times did you take the ACT?

What is your home state and your budget?

Before you bump again, give people a chance to wake up and drink their coffee. What is the breakdown of your ACT scores?

Try SAT. For top engineering schools like GA Tech, Cornell, and UIUC, chance with ACT 27 is extremely low.

I took it twice. First time even worse. Second time ACT breakdown is E: 29, M:29, S27, R:21
I’m really disappointed by my scores. I struggle with time on the ACT, so hopefully can do better on the SAT. What would be a competitive SAT score to aim for?

What’s your approximate class rank? Cornell requires that you send ALL scores so they will see the lower ACT score as well. I’m afraid without a really decent showing on your SAT, you will have difficulty getting into a school like Cornell (especially th engineering school). You haven’t even mentioned your ECs so unless they are really solid you have little to no chance presently ED at Cornell. Good luck on the SAT exam!

Thanks! I have a lot of ECs related to engineering and science like robotics clubs and competitions, summer internships, honor societies, and math and science tutoring. I’m confident can get a better SAT score than my current ACT. I also forgot to mention that I’m an international student.

My school doesn’t offer a class rank, but based on my gpa relative to other students, I’d estimate it to be in the top tenth of my school at least.

All right. Good luck with the SATs

To answer your question. Yes, your ACT score is a deal breaker. However, you can give yourself a shot with a high SAT score.

Some people do much better on SAT than ACT and vice versa. The two tests are structured differently. Give the SAT a try and good luck.

Aim for 1500 in CR+M.
