Yeah, you've gotta do it soon, because then you'll miss your chance and it may not come up again. Considering the size of your classes. Don't put too much pressure on yourself. Think of it as practice. If you fail miserably, it doesn't matter because you took the effort and gave it a shot. It'll be easier next time. Also, if it works well, even better. Just remember, nothing wagered, nothing gained. It's worth it.
