Barron's SAT Writing Workbook Accuracy?

<p>When I first took the diagnostic, I missed 2 questions out of 49. This was surprising because I normally miss about 6 or 7 on the blue book questions. This made me believe that the Writing Workbook was too easy but when I took the practice tests, I consistently missed about 11-14. All of the questions seem to be at the level 4 or 5, and a lot of questions are mixed around in difficulty rather than progressively more difficult. I missed question #1 for crying out loud! Am I crazy or is this a common problem?</p>
