GMAT contains 41 questions on Verbal Ability, of which as many as 15 are on Sentence Correction. For securing a high score in GMAT, you must answer the Sentence Correction questions not only correctly but also quickly. There are hundreds of ways in which one can make grammatical or syntactical mistakes while writing an English sentence. We have scanned over 900 Sentence Correction questions in actual GMATs, and have found that they feature just 25 types of mistakes. After lucid lessons on both basic and subtle grammatical concepts, we have explained each of these 25 types with authentic examples, and have given you, for your practice, 20 sets of 15 questions each, of the same types and levels of difficulty as in an actual GMAT. These are followed by a masterly analysis of each question. So, when you actually face such questions while taking your GMAT, you would be doing so the twentyfirst, and not the first, time! Unlike other Guides which first identify the correct answer to a question and explain why it is the correct one, this Ideal Guide teaches you how to arrive at the correct answer by yourself in the shortest possible time, since that is what you have to do when you sit for the test.
