Please note

The validation quiz at the end of each workshop is for our benefit (the workshop hosts) so we have a gauge of how participants are going and whether you are learning key topics from the workshops.

And when the validation quiz is completed within 24 hours of a workshop, we use it as confirmation of attendance. But again, just as a way for us to track aggregate participation.

To be clear, the quizzes are NOT to penalise participants. Think of the quizzes as a way of thanking us for the 100+ hours we spend each week delivering a workshop. When you complete the quiz immediately, it's you acknowledging our efforts and showing your appreciation at the end of each workshop.

We are here to help each and everyone of you learn, develop and become successful with Apache Cassandra. Thank you for attending our workshops!
