Where's this quiz?

In Unit 4 of ROS Basics(Understanding ROS topics), there’s a Quiz apparantly. But where’s it?
I see only the instructions to the quiz, but not quiz. There’s no link or anything like that to start the quiz.
Thank you

Hello @abdulbasitisdost,

The Quiz is explained in the notebook. You just need to follow what the instructions are asking you to do. It’s like a regular exercise, but a bit more complex. You don’t need to follow any link or go anywhere else.
