Priscilla Chan, Mark Zuckerberg on their hardest school subjects

Facebook CEO Mark Zuckerberg and his wife, Priscilla Chan, got real with their social network fans on Wednesday, revealing what they considered the hardest school subjects they had to tackle. Music is not an easy subject for her, she said on a live-streamed Facebook video posted on Wednesday. “We want to make sure she grows up with good Zuckerberg pitch,” he said on the video, leaving some people to wonder whether Max will join Facebook’s a cappella group, the Vocal Network, when she gets older. The video was part of Zuckerberg and Chan delving into the educational efforts in their philanthropic entity, Chan Zuckerberg Initiative LLC. “We believe that every individual has an incredible amount of potential that (they) may not be able to manifest because of various circumstances and conditions,” Chan said.
