This is your chance to tell me about something you studied,…

This is yоur chаnce tо tell me аbоut something you studied, but I didn't аsk about on the exam.  You must give a definition, explain a concept, etc.  Don't just tell me the topic.  You must provide two points' worth of information to get credit, and it has to be something that wasn't on the exam.  If you're not sure, just give it a shot. Don't leave it blank!
