Writing MC

<p>I have a question about the writing multiple choice, namely the error identification questions. I find that this always brings my grade down a lot compared to the other sections of the test. =/ I end up choosing a lot of wrong E's. The sentences seem to sound okay to me, until I find that if I start looking for a speific error it's bound to come up. What types of errors should I be looking for, such as dangling modifiers and redundant words?</p>
