So, I know I need a lot of work on the fundamentals of grammar. I have several books - Manhattan'sFoundations of GMAT Verbal , Kaplan'sVerbal Foundations , and Max Morenberg'sDoing Grammar . I have started working out ofDoing Grammar , but how do I know when I have a solid level of understanding of the basics to transition to Manhattan's SC Guide? I have signed up for Magoosh, but the intro lessons seemed a bit over my head.
