Online Practice

Contests and activities (posted in the Inventory section) have been broken down into manageable sections and turned into online quizzes (using Google Forms).

The Individual Contests have been set up to mark your answers (which are almost exclusively numerical). In each quiz, you may complete as many of the questions as you want. After you click "submit", then "view score", you will be told how many you got correct, and you will also be given hints to each question. These are intended to help you try again if you didn't get them right the first time (or didn't even know where to start).

The Paired and Team Activities have much more complex solutions (for the most part), so they are not set up to mark your answers. After you click "submit", then "view score" (or "view accuracy"), there will be feedback available for each question. In some cases, it will provide the answer. Other times, it will provide one of many possible answers or explanations. And other times, there will be a link to an image. You can check for yourself whether you got the answers right or not.
