After spending 15 years in jail, Patric McGuinness is now a leader in his community who volunteers with at risk kids and always advocates for the power of a second chance.

Given his own second chance, Patric has decided to study for The Knowledge, an intense series of written and oral exams taken to be certified as a London cab driver. The test requires cabbies-in-training to memorize thousands of the city’s streets, and can take some hopefuls years to complete.

To practice for the exam, the “Knowledge Boys” and “Knowledge Girls” have created a Facebook Group to serve as a forum and support system where they provide tips and encouragement to one another as they study.
