I'm in a TON of extracurriculars as well as challenging classes and it's definitely manageable if you can stay organized. There's obviously only five days a week that extracurriculars will meet, so if you're interested in a lot of things, you'll have to be pretty selective about what you pick, especially if you're an athlete, but lots of clubs are really flexible about letting you try different things before committing. Just know that if you try out for a sport and you make the team, you're in and that's that - you can't really experiment with the sports. You'll find at least one assistant principal or sometimes the principal at every athletic event, but the same can't be said for every club event. Athletics definitely receive more funding than clubs (we've had a speech and debate team for years but they only just now got on the budget), but we do have lots of fundraising opportunities and lots of places in the community that are willing to help with fundraising (Garlic Knot, the Shack). The extracurriculars that demand the most commitment are probably yearbook and newspaper because we have deadlines to work with, but other clubs do a lot of activities as well: GSA gives presentations to faculty about how to make their classrooms more accepting, Community Relations organizes and runs Make a Difference Week, LINK organizes and runs activities specifically for freshmen, etc.
