Practice Times

While you read the textbook, you will also see Practice Time activities after most topics, marked with a special icon.

These problems stay in the lesson. They give immediate feedback so you can apply the idea you just read, including 3D structures and animations that bring the chemistry to life.

Take Note

Practice Time is in-page practice while you read. Orbit quizzes are the course-objective loop: they update My Path and are how Orbit keeps you on track for exams. Use both. Read and try the in-lesson problems, then let Orbit quiz you on the objectives for that chapter.

The pages that follow show the other textbook tools you will use in Learn — handwritten drills, 2D and 3D structures, and the drawing editors. Many of the same tools also open inside Orbit chat when he launches an app.
