I’m assuming that the 4.0 that you just quoted is the unweighted 10th-11th grade GPA (since you said all Bs were in 9th grade)?
It may help to calculate your UC capped and uncapped weighted GPAs using Roger Hub:

With an unweighted 3.94 (4.0 in 10th and 11th grade) and 13 APs (if I counted correctly), wouldn’t your weighted GPA be higher than 4.4? Or are some of those APs self studied?
