Sentence Correction (1 of the 7 books in Manhattan GMAT's Preparation Guide series) takes the guesswork out of grammar by presenting every major grammatical principle and minor grammatical point tested on the GMAT. Students learn to master the rules for correcting every GMAT sentence and to avoid relying solely on their (imperfect) ears. The book offers a unique balance between two competing emphases: test-taking strategies and in-depth content understanding. Practice problem-sets build specific foundational skills in each topic and include the most advanced content that many other prep books ignore. As the average GMAT score required to gain admission to top b-schools continues to rise, this guide provides test-takers with the depth and volume of advanced material essential for succeeding on the GMAT's computer adaptive format. Book also includes online access to 3 full-length Simulated Practice GMAT Exams at Manhattan GMAT's website.
