Worth retaking science SAT subject tests?

I’m a rising senior who is looking to double major in business and engineering (probably CS). Right now, I have a 720 in Bio E and a 720 in Chem. I’m looking at applying to top schools like UPenn, so are my lower scores in science SAT subject tests worth retaking?

I’m not sure if its worth all the time to relearn chem or bio, and I have an 800 Math II and a 750 US History right now. Would appreciate any input!

SAT 2’s are the least considered test and they will not care about them that much.

From Penn’s website:

SAT Subject Tests are recommended but not required. Applicants who do not take SAT Subject Tests will not be at a disadvantage in the admissions process.

also for engineering (recommended)

Math Level 2 and a science test (preferably Physics for Engineering Applicants)

So just send in the Math and US history or take the physics test.
