Thanks for replying. To clarify, it’s merely based on the counselors and priority goes to people who requested less APs. I have not contacted them as they strongly emphasized for us to not do that. Our school doesn’t ration it fairly or in numbers but on the availability of classes. So some requested only 4 and later ask for a course request to change a class to an AP that has enough room. I didn’t realize this so couldn’t use this strategy earlier.
