Twenty six questions on Units 1 to 4, which should take about twenty five minutes. There is no clock. There is no immediate feedback. You find out which topics you need more practice in after you are done.

The page fills the screen while you work, so there is nothing else to look at. The scratchpad, the calculator and the graph are under every question, and your work saves as you type. You can save and close at any point and pick it up where you left off.
