I am sure no one enjoys grammar on the weekends. I started a month back and and after going though basics again and again, I have started assimilating concepts.
How long do you think it takes to get familiar with grammar rules? I am specialty struggling with sentence structure, Clause and phrase. While reading grammar books, it all makes sense. But while solving question, it become very difficult to identify structure and parts of speach.
Main problem is to decide whats sufficient for GMAT format. If you study only fro GMAT perspective, you tend to leave basics and concentrate only on 8 error types. While entier grammar will be very tedious to study, what is the minimum needed for gmat? I think it takes some time to digest grammar.
