High school senior year comes with rapid coming-of-age lessons and high-stakes college entrance exams, equal-opportunity stressors that affect both the rich and poor. Jeff Hobbs joins host Krys Boyd to talk about the Los Angeles boys he followed for 12 months to tell their stories of working toward their higher-education goals amid atmospheres of racism and privilege. His book is “Show Them You’re Good: A Portrait of Boys in the City of Angels the Year Before College.”
