Does this make sense? (School related, please see details)

Sorry for the unclear question, I wasn’t really sure what to ask. So here is the background story. This coming school year is my senior year of High School. At the end of the school year, I signed up for English 4 honors. But after school ended, I decided I did not want to take that class. So I emailed my guidance counselor, and asked her if I could change it. She said, “Yes, I made an appointment for you at 8:45 am on August 21st.” First of all, by that time, school is just days away, so how the HELL am I going to finish all the summer work? Second of all, I may not even get the class I’m asking for. So I sent her another email explaining my concern for how late the appointment was, and she said the earliest appointment was August 6th, and they are probably all taken. I realize I probably did not need to rant this much to ask something simple; but why in the world do I need an appointment to get a simple schedule change? Maybe some of you are more familiar with the school system than I am and can explain this absurdity to me.
