The repository is meant to be a quick self-assessment to help you gauge your progress. Consider doing a quick review of notes / exercises beforehand. Put your notes and exercises away before starting.
You are to attempt this assignment WITHOUT ANY OUTSIDE RESOURCES. No notes, no reviewing old code, no web searches, no AI. Once you have cloned and opened the code in VS Code, start a time for 20 minutes. Try your best to complete the exercise(s) within the time.
If you are not finished after 20 minutes, that is OK! But it is a signal that you should do some extra practice/review. I strongly reccommend coming by office hours or tutoring for review. Make a note of what parts were difficult or what you got stuck on and bring those notes for a review session.
