I had no reason to pick this book up other than a passing interest in standardized testing (never taken the SAT, though). It’s a memoir of an experimental year-long project, in the same mold as an AJ Jacobs book. 

It was entertainingly written and also out of date (SAT was overhauled, post-pandemic standardized testing is a different landscape, rise of test-optional schools, computer-based tests, etc.).
