Mercury is stupid and Neptune sucks.
The AP Biology students got their article on Success that will be used in the school-wide write which is happening next week. Next Tuesday, specifically. That's where everybody in the school gets a writing prompt and cites articles to support their ideas. I'm pretty sure that's what happens.
