Fun! A few quick toughts...Spencer's clickable code of points is great for this. It includes every skill, not just the elite skills...so all the skills an NCAA gymnast might perform will be in there (and his gifs often feature college gymnasts). In each entry, Spencer includes a "known as" section, which could be very helpful, as it gives some of the nicknames that gymnasts and coaches use in place of more formal names (e.g. "double lay," "tsuk," "full in," "chush," etc.) As far as getting a good understanding of the skills that are most common in the NCAA, watching a ton of meets and following the athletes on social media (as I'm sure you're already doing!) would be a great way to get familiar with the lingo and the types of skills they tend to perform. The comments section of Instagram posts showing routines and practice skills will often include gymnast shorthand language about skills that could be useful as well. Good luck!

@emily-lee I actually hadn't thought about social media. (I very rarely use it, and really only for author stuff.)  Thanks!
