Two months of studying paid off today. I took my ACE exam for ColdFusion 8 and passed with a 98%, which also means I qualified for the Advanced status. The Web Application Construction Kit is all you’ll ever need to become a CF Ninja. For the exam I’d recommend reading the first volume cover to cover. Additionally I found the ColdFusion MX 7 Certified Developer Study Guide to be very useful. Even if you don’t need it for your job challenge yourself and go for it.
