Orbit is your OpenOChem chemistry tutor. He watches which course you are in, which learning objectives you have started, and where your accuracy is slipping — then points you at the next quiz, chapter, or explanation so you stay on track for exams.
This section walks you through that loop: meet Orbit, select your course, work the course objectives, and ask him in chat for a new quiz. After that, you will learn the textbook tools used throughout Learn: Practice Time problems, 2D and 3D structures, drawing questions, and the colored callouts.
