You may want to re-run that. It’s nearly impossible to get above 4.30 if you include 9th, 10th and 11th grades, especially if you’ve had any Bs. In reality, it’s tough to get above 4.20.
My son calculated out to 4.32 and I’ve never seen one higher. He had 25 semester hours (which is low for most schools), all As. The reason he could get that high is that he went to a catholic affiliated prep school and his religion classes weren’t included in his total hours as they don’t fall into a-g. That lowered his total calculated hours. As you can see, the fewer classes one has, the more impact the honors/AP/IB bonus has.
The only way to get to 4.33 with 2 Bs is to have 16 semesters of A. I seriously doubt that in 3 years you only took 9 classes (16 semesters of A and 2 of B). My guess is that you counted more than 8 semester hours of honors/AP/IB.
