I would echo @one1ofeach’s advice to - at the very least - probe the question with AOs. Don’t forget too that with placement tests you can not only continue to progress academically. but may find yourself (assuming your current coursework presents well on your placement tests) in classes with older kids even though you’d be nominally a 9th grader. All but one of my kids’ classes (a mandatory intro english class) are filled with older kids.
