I think she has an excellent chance at Cal Poly, but I would still call it a reach.
She has amassed a very impressive record, but in a weird way, it has had a negative impact on her Cal Poly GPA. The number of classes she’s taken, which in most paradigms would be a strength, diluted the impact of the AP weighting. The algorithm used to cap at 4.20 treating everyone there and above the same. There’s speculation that they’ve either removed the cap, or that it’s higher, because they report higher GPAs now. No one knows for sure. My guess is that it is capped at 4.25 now, as their accepted student profiles for each college top at 4.25. The CENG range is tight 4.17-4.25. A 4.22 is still very strong.
As for her AP scores, no impact on admissions. In order to find out if she’s ready to use them to start in Calc III if she chooses Cal Poly she should call the math department and ask for old tests from I and II. If she does ok, or is just a little rusty, she should move on. If it feels foreign, she should repeat.
AE is certainly an option, but ME is too. The ME route is less systems oriented, and oriented more to aerodynamics if one chooses that route. My son did. He did his MS in aerodynamics and had multiple aerospace industry options. He ultimately went a different route though. They would be similarly competitive though, so AE is probably the way to go. Both would be reaches.
MateE would be a match though, as would General, with the intent to switch to AE.
If Cal Poly is strongly in consideration, she can boost her application by doing a job, even as a volunteer, even 1-2 hours per week. Every point will help.
Also, make sure that she reads the application carefully. It calls for including some middle school classes. If missed, a student’s chances are greatly reduced.
I’m highly biased, so take this with a grain of salt, but the Cal Poly experience will be different than UCD and UCSB.
Classes are smaller and nearly all of them are taught by instructors with terminal degrees, including labs and discussions. Calculus for example is capped at 32 students per section.
The bigger thing though is that Cal Poly students do really cool things in labs and clubs. CubeSat was invented there. As a result, they have not one, but two CubeSat clubs. Bill Nye based LightSail out of CP because he said CP is the center of the CubeSat universe.
My son has friends at SpaceX and NASA. One of his best friends worked on the Webb telescope. Getting a job won’t be a problem.
The downside os that for better and worse it is isolated. It’s also less diverse, even though they are making huge efforts to mitigate that.
OK, end of sermon. She should certainly visit and ask for a deeper tour of the facilities, especially the CubeSat labs.
She’ll have a great future no matter where she lands.
