The mastery bar reflects our confidence that you truly understood the learning objectives in an assignment, will retain the understanding, and are prepared to advance to the next topic. As you answer questions, we incorporate the results into the full history of everything you've done in Alta assignments, quizzes, and tests. We use this history to update the mastery bar, which is shown at the top right of your screen.

When your mastery bar reaches 100%, you are done with the assignment. How long it takes you to reach 100% depends on how you answer the questions in the assignment. Everyone learns at their own pace, so don't worry if it takes you a little longer!

The mastery bar represents our best estimate of your mastery, so it will move up and sometimes down, reflecting your progress. This means that if you get a question wrong, the mastery bar might go down, since we now have a clearer view of how much progress you’ve made toward mastering these topics. This is not a punishment! We don’t think of the mastery bar as “how much work you have left,” but rather “how much more you have to learn before you master the topic.” Don’t worry — you can use the answer explanations to learn the material, and your mastery bar will go up as soon as you start answering questions correctly!

In addition to the assignment-level mastery bar, you also have access to a more fine-grained view by clicking the V icon. This will take you to a screen which shows your mastery on each Learning Objective for the assignment.
