AP classes denial from school

Yeah, the school specifically sent an email to not email and only fill out a course request form. The school is refusing to talk about it. I’m guessing they don’t have enough spots. Also I was typing in a hurry and didn’t care for any grammar mistakes lol. I get that 4 is a lot, but I just believe in my academic capabilities and feel this is taking away a chance that other students in the past classes all had equal access to. It is unfair as some students had exactly the same course as me along with an AP they wanted while I didn’t. It’s un fair because this decision wasn’t based on grades or any sort of merit. I understand that you did not see this aspect because no one can understand the situation given my little explanation:)
