(AP) — An online course on effective giving plans to offer lessons from actor Patrick Dempsey along with advice from Warren Buffett and other prominent philanthropists.

Students in the class that’s now scheduled to start in early April will be able to help decide how to give away at least $100,000 of Buffett’s sister, Doris’, money.

Dempsey agreed to join the Buffetts, baseball legend Cal Ripken Jr. and other philanthropists in sharing lessons they learned from their own charitable efforts.

The class is backed by Doris Buffett’s Learning By Giving Foundation and Northeastern University. Anyone interested in the course over the age of 13 can sign up now at www.learningbygivingfoundation.org .

This will be the second time the course is offered. Last summer, students helped pick 40 nonprofits to share $130,000 in grants.
