I'm in elementary school and here is what we have.
We do have P.E. on Mondays, Tuesdays, and Thursdays though it's different for each class. My school doesn't have uniforms as it is a public school. We have instrument classes on Fridays, choices being Strings (Violin, Viola, Cello), Band, or Choir. In elementary school, we don't have lockers. We don't have a bus yet. I walk to school, but some kids bike or have their parents drive them. In elementary, we don't have showers.
