AP Score 3 Submission

My junior year of high school I took AP Lang and got a 4 on the exam and AP Physics 1 and got a 3. I am wondering if I should submit the 3 as, while it’s not the best score, I don’t want the admissions officers assuming it is worse than it is. An important note is that I am applying for Engineering- would the 3 in physics be especially detrimental because of this?

I’m also wondering, should I submit this 3 to schools that are more competitive? I am applying to a large range of schools- from Purdue to Cornell, and I was wondering if submitting the 3 to the more competitive schools would be a bad decision as these schools are used to seeing solely 4s and 5s.

Thank you!!
