@navyman – there should be a timer (which counts down) in an orange block above the questions, in the middle of the screen, when taking a test. If this is not displaying for you, please kindly let us know which operating system and internet browser you are using so we can investigate further.
My daughter used this website for extra practice as I had only found this tool a few weeks before the actual test. It exposed her to different question styles and the timed tests helped her immensely in getting some practice under time pressures. Happy to say she passed. Because of this resource I was able to help her prepare without the need for a tutor.
