PSA: Make sure that you know how to debug VSCode and worksheets!

Some of have reported issues with VSCode, or having trouble with worksheets. The CS-214 final may be on computers, and we will not able to help you debug during the final.

A malfunctioning setup (VSCode, SBT, worksheets, etc.) will not be a valid excuse to get your final grade reconsidered, so now is the time to bring these issues to a help session, and get our help to fix them. You can ask during all help sessions.
