"Best chemistry course I've ever used. Chapters are compact but well-written and logically structured. Content is made interesting and infinitely useful to undergraduates. Highly recommend for one learning organic chemistry for the first time."

Common questions
Is this annual or one-time?
Annual. $99 covers one year of access to the full Premium course. There is no auto-renewal and no card kept on file — you pay once and we'll never charge you again without you explicitly choosing to renew. We'll email you about a week before your year ends so you can decide.
What happens at the end of the year?
Your premium access expires. The two e-books you've downloaded are yours to keep forever, regardless of whether you renew. Your account, bookmarks, and history are preserved in case you renew later. Renewal is optional and at the then-current price.
When do I receive the two e-books?
The complimentary e-books are emailed to you the day after purchase, once the 24-hour refund window has passed. Once delivered, they are yours to keep forever, regardless of whether you renew.
What if I'm not satisfied?
We offer a 24-hour money-back guarantee on all new Premium Subscription purchases. Email us within 24 hours of purchase with your order number and we will refund the full amount. The two complimentary e-books are emailed to you the day after purchase, once the 24-hour window has passed, so they are not affected by refunds. See the full refund policy for details.
