GUEST: JON CARSON, CEO, COLLEGE GUIDANCE NETWORK.  Public high school counselors are overwhelmed, with caseloads of up to 700 students in the most extreme cases.

What's a high school senior to do? Amy talks with Jon Carson about College Guidance Network, a new content company that is helping to bridge the guidance gap.
