Currently in the About section of AntAlmanac,

"Search bar to easily find classes by department (e.g COMPSCI), section code (e.g. ICS 31), and keywords (e.g. artificial intelligence)"

This refers to ICS 31 being a section code which isn't true. This should be a code formatted in a way like 36040(an actual ICS 31 section code) for accuracy.

With further discussion, another idea would be to call it course/course number and keep the ICS 31 example because that was the original meaning. Any opinion on this would be much appreciated!
