Also known as "senior class n+1," where n equals the year of the current senior class. Many juniors are attempting to fill their AP requirements and/or taking Capstone, which is why you occasionally hear a gross sob from a junior homeroom.

This can separate friends by book-smarts and level of fine art skill, as well as create a very politically charged atmosphere within the classrooms.
Most people don't join West Shore in junior or senior year, so the class begins to really know each other. There's still drama, but at least it has more variety.
They will never win Powderpuff.
