This extension shows the course description for current highlighted text
Have you ever looked at the MIT course numbers and wished you knew what the heck they stood for? Well, wish granted.
Just highlight a course number and a popup will show you the course description and links to the course evaluations. If you also are just talking to somebody who mentions a course number, you can open the menu and search that course number from there.
With this tool, you no longer have to feel stupid when talking to upperclassmen or those people who memorize the bloody course catalog. It also makes understanding major requirements so much easier when it's not just like: "Hey there. Here's a list of a million numbers. Take a couple these. LOL." Now, you can understand what those numbers are just by selecting them and not having to go manually search every single one.
