## test

You'll be presented 10 questions out of different categories.

Questions range from answering what output a certain block of code would produce to just fact-checking.

There is no time limit, so no stress.

You can go back at any time during the test. So you don't need to supply an answer immediately and you can correct an answer when you've already moved on.

While I certainly can't check it, it 'd be nice if you participated without looking up the answers on the big old internet. What would the point of taking this test be otherwise?

Found some errors? Wish to expand on something? You'll be given the opportunity to supply feedback at the end of the test.

Good luck!
