I used Mock labs and the new Poly-Labs for my preparation. I found graded labs a good way to check you knowledge before the exam. Since you will see directly, which topics will need more preparation and you can focus on these. For this Lab Workbook Volume I is also the best i have seen. Good way to concentrate on a specific topic and learn all of it's functions and features. Thanks to IE. Well done.
