# We save a series of custom events when a student takes a quiz. These events
# give us interesting insights into quiz-taking behavior.
#
# We want to write code that uses these events to answer questions
# about a particular quiz attempt.
#
## The Events
# We store the events in a series of records stored as JSON. There are
# six different types of events:
# - `start_quiz`: The student started taking the quiz
