I'm totally lost with this quiz. What is System.index and why isn't it explained in the video, but appears in the quiz?

There are also other questions in the quiz that asked throw exceptions that don't have a specific catch clause in the example code. When selecting the exception won't be caught, it says the answer was incorrect. Can anybody explain this? This course feels like it has some many holes when it comes to introducing exceptions.

I think you're referring to "System.IndexOutOfRangeException", and it's not necessary to be familiar with that specific exception as long as you notice that its a "System" class exception. That's the important fact that allows you to choose the correct answer.

And while several questions don't have a specific catch clause in the example, some do have a generic catch clause for the exception class. So those will still be caught by the generic catch.
