Choose the best response by clicking on it. If both the first and second choices are correct, then choose the third option: '(Either is correct) as this will be the best answer possible.'

The timer gives you 15 seconds to find the answer. It notes your errors but it only shows you the correct answers at the end.

If you don't use the timer you see the correct answers immediately, and in many quizzes you can click on Another example to see a similar word or sentence.
