hi guys, I just come back from the test center and I got 88% of the test. I have been prepared for the test for one and half a month. I feel that: 1. Stick to the K&B book, it is enough for you to pass the test. 2. make sure you understand all the self test of each chapter. 3. whizlabs and other mock exam are harder than the real exam,if you can get 60& of those mock exam, you are ready to go( I always got 50/72 on those exams). 4. take easy and it is just a test.
