Our instructors are leading practitioners and subject matter experts. On average, each has 20 years of experience in his or her selected field. This experience enables them to go beyond the curriculum to provide context, tips, and practical real-world examples to help you better understand and apply the course content right away. We vet each instructor thoroughly, to ensure they meet our high standards of quality for content and presentation. And we enable our users to peer-test and review all of their courses.
