Featuring chemist-developed content, OWLv2 is the only system designed to elevate thinking through Mastery Learning, allowing students to work at their own pace until they understand each concept and skill. Each time a student tries a problem, OWLv2 changes the chemicals, values, and sometimes even the wording of the question to ensure students are learning the concepts and not cheating the system. With detailed, instant feedback and interactive learning resources, students get the help they need when they need it. Now with improved student and instructor tools and greater functionality, OWLv2 is more robust than ever. Visit www.CENGAGE.com/owlv2 to learn more.
