Bests & Worsts Reviews from Amazon

You can stop looking now. This is the book you want. My son comes from a country where school goes Ron 10th grade, and the education is really more like a 6th-8th grade education, depending on the subject. He had two and a half months to study for his GED. He had never seen an algebra problem before. He had never learned US social studies material. He had never done earth science, biology, or chemistry. He had never written a proper essay. We went though this book, and he passed every test the first time! This is life-changing!
