... start on next year's new website design even before this year's competition even started....

Everyone in your classes automatically assumes you have the highest grade in the class

You skip most or all of lunch to play games on the internet

[artdutra04]

...When designing your team's website you write your own PHP/MySQL CMS consisting of thousands of lines of code, just because you don't like any existing ones.

...When you bring your laptop to every class, and take all your notes in Notepad. (It's much loads much faster than OpenOffice.) When your teacher has a break in their lecture, you either open Inventor and start designing parts, or you open Dreamweaver and start writing PHP code.
