I am a native English speaker, and I am having some trouble with the sentence correction portion of the GMAT. I can hear many errors just by reading the sentence, which allows for the elimination of choice A, but I tend to falter on the verb tenses, clause/phrase, and pronoun agreement.

Is there any good advice on test prep for this section (ie: books, study guides, etc)? I really need to increase my efficiency, so I can spend more time on RC and CR.
