Improvement. How much will this help me?

I have had a 3.5 UW GPA through my first three years of HS (straight B first semester of Jr year because of illness before finals, but 2nd semester got 3 A’s and 1 B in AP Chemistry, and a straight B first semester of freshman year because I couldn’t check what I was missing since the tech guy put my username in wrong).
My weighted GPA at school up to this point has been a 4.13 between 9-11 and 4.3 between 10-11 (this includes a C- in Spanish 3 one semester, the avg in there was pretty low).
I have a 33 ACT with a 10 on the essay portion, and have various EC’s that I don’t/can’t list off the top of my head.
Along with that, I have gotten my final results back from my senior year and have received all A’s (AP Government/Economics, APES, AP Calc ab, AP psychology and english 4, so 4.8 W, 4.0 UW). Will this help me a lot? Or is it too late for the first semester grades to even make a difference? (Brought my weighted GPA up to a 4.3-4.4 range, idk about UW)
A list of my reach schools (i have already gotten accepted to Santa Clara and Chapman as safeties, but didn’t get into boston college)
USC
University of Michigan (Deferred EA)
UCLA
Cal Poly SLO (Idk if this really is a reach or not)

IK USC asks for mid year grades, so will my straight A semester help me in my application? (I am a legacy btw)
Another slight question, when a college asks me to report my grades, should I also include the grade I got in my sport? (Wrestling) Thanks!

I think for those colleges that ask for a mid-year report it could definitely help, or at least somewhat get put into consideration. Would it have been better to have had that 4.0 before senior year? Yes. But it could make or break your application if you are borderline. Your ACT is high, extracurriculars seem strong, and if your essays are pretty great, a college might just need that last semester to make your admittance a for sure for them.

idk about the grade thing, my school doesn’t give out grades for sports. I’d say include it just in case, especially if the grade shows excellence in the sport.

@kw7998 it was literally just based on attendance lmao

@jj1999 perhaps if you include that in an essay or a box that some colleges provide for expanations on that kind of stuff (for example my UC application had a box for this kind of stuff) then colleges will be more inclined to look at your latter grades. I mean tbh the whole thing sounds like it could just be a great essay in general as long as you don’t cross the border into too cheesy.
