Not average. Not even close. Avrage is 3.0-3.2 GPA…
Do you mean the AP test? It’s not generally important, since there is no need for you to report AP test scores, and, for American colleges, they are not considered for admissions.
If you may fail the class, that may be an issue.
Stanford: Lottery ticket, but unless another colleges appeals to you a lot more, apply.
Reaches: USC, UCLA, Berkeley, Cal Poly (low reach)
However, if your UC weighted capped GPA is over 4.2, Berkeley and UCLA move to low reaches.
Target: Pepperdine (high target), SDSU, UCSB
However, if your UC weighted capped GPA is over 4.2 UCSB moves to Likely (most likely to be accepted, but there is a chance that you will not).
Safety: Saint Mary’s College of California, Cal Baptist
Those are, however, your academic chances. At an income of around $100,000 a year, some may be unaffordable. Although both USC and Stanford are full need met colleges, their idea of full need may not match what your parents can actually pay.
In general, you need to run NPCs on every one of those colleges, and see whether your family can afford them. If not, you will need to look for colleges which will provide better financial aid, and, based on your GPA, look for colleges which will provide merit aid. Your GPA is very good and you likely will qualify for merit aid at any number of colleges.
