Some of the questions require that you enter the answer. if you use contractions, use the apostrophe located on the question mark key from your keyboard. Optionally, you are not required to use contractions. For example:

I haven't or I have not are good answers. But I haven´t uses a different punctuation mark that looks like an apostrophe, but it's not, so it will be marked as incorrect. If you feel something was marked incorrectly, tell your teacher about it so he can correct it manually.

Go ahead and take the test.
