I read it around 2010-11 when my older child was doing the college thing. It was useful, as were most but not all of the other books I read in that time period…the Hernandez (A is for Admission), Admission Matters, the novel that was recently made into a movie - Admission, The Neurotic Parent’s Guide to Admissions which made me literally laugh out loud as I read it, Admissions Confidential, Crazy U, Acceptance, and the extremely useful Paying for College Without Going Broke which i picked up in a college bookstore after a tour for $1 - a previous year’s edition. I liked that one about the California guidance counselor that tracks 3 or so specific kids through their admissions process.
With my first kid I swear I read more than 10 books on admission. With the second, really none.
