Wow, I feel like such a creeper for asking, heheh, but I have a character about to finish high school at Cody High. She's literally getting her diploma the weekend the story opens.

What I want to know is: What do they do for marching practice at Cody High? When do seniors "finish" their year (AKA in my high school seniors finished classes two months before everyone else and had a week or so of marching practice before graduation and poof, they're done)? What is the general schedule of the day? Do the kids there have lunch bells (a bell rings and oh, it's A lunch, everyone in A lunch go eat, then one for B lunch, C lunch, ect.)? What time does/do lunch/es start? What time does a typical school day end?

Many thank yous to anyone who can answer
