Download or read book The Perfect Score Project written by Debbie Stier and published by Harmony. This book was released on 2014-02-25 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Perfect Score Project is an indispensable guide to acing the SAT – as well as the affecting story of a single mom’s quest to light a fire under her teenage son. It all began as an attempt by Debbie Stier to help her high-school age son, Ethan, who would shortly be studying for the SAT. Aware that Ethan was a typical teenager (i.e., completely uninterested in any test) and that a mind-boggling menu of test-prep options existed, she decided – on his behalf -- to sample as many as she could to create the perfect SAT test-prep recipe. Debbie’s quest turned out to be an exercise in both hilarity and heartbreak as she took the SAT seven times in one year and in-between “went to school” on standardized testing. Here, she reveals why the SAT has become so important, the cottage industries it has spawned, what really works in preparing for the test and what is a waste of time. Both a toolbox of fresh tips and an amusing snapshot of parental love and wisdom colliding with teenage apathy, The Perfect Score Project rivets. In the book Debbie does it all: wrestles with Kaplan and Princeton Review, enrolls in Kumon, navigates khanacademy.org, meets regularly with a premier grammar coach, takes a battery of intelligence tests, and even cadges free lessons from the world’s most prestigious (and expensive) test prep company. Along the way she answers the questions that plague every test-prep rookie, including: “When do I start?”...”Do the brand-name test prep services really deliver?”...”Which should I go with: a tutor, an SAT class, or self study?”...”Does test location really matter?” … “How do I find the right tutor?”… “How do SAT scores affect merit aid?”... and “What’s the one thing I need to know?” The Perfect Score Project’s combination of charm, authority, and unexpected poignancy makes it one of the most compulsively readable guides to SAT test prep ever – and a book that will make you think hard about what really matters.

We’re all born with a certain “imprint” for work that makes us come alive. This is your "Sparketype®," your DNA-level driver of work that lets you know, deep down, you’re doing what you’re here to do. Work that motivates you, fills you with purpose and, fully-expressed in a healthy way, becomes a main-line to meaning, flow, performance, and joy. Put another way, work that “sparks” you. Sparked draws upon years of research, experimentation, more than 25-million data-points generated by over half-a-million people, and hundreds of deep-dive conversations with luminaries from science to art to industry and wellbeing. Award-winning author, serial wellness-industry founder, and host of the top-ranked Good Life Project®, Jonathan Fields, and his team at Spark Endeavors, developed the Sparketype imprints and methodology that is the basis of this book. In this book, Fields and his team will help you: Discover what sparks you, what drains you, where you stumble and come alive, so you can reclaim a sense of direction, control, and purpose; Understand the “real” reasons certain experiences, jobs, and roles leave you empty and know how to make things better, without having to endure big disruptive changes; Learn from real-world, relatable stories, case-studies, and data-driven insights; Identify the action steps to begin immediately transforming the way you work and live. Sparked takes you deep into the world of the Sparketypes, revealing an entirely new depth of insights about what makes you come alive in work life, along with what empties you out and trips you up, so you can avoid those life-drains. You’ll discover tons of case studies, stories, and real-world applications, creating a comprehensive guide to help you discover what you are meant to do and how to get started.
