Just a quick heads up, with the recent inclusion of TEM in the CHUF syllabus the exam has become a very different beast, i did it about four weeks ago and trust me its a tough exam. You will find about 40% of the 40 questions are threat and error management and if you don't properly prepare for it you will be in for a surprise. I know plenty of guys and gals who were like my friend said CHUF was real easy blah blah blah..... guess what most of them failed it...
