I went through one of those week long crash courses myself in Norfolk, Va. under Gene Hornberger's tutelage. I had fun learning and having my head opened up and tons of info poured in until it ran back out. I did think that in the test I took, the questions were to see if they could trip you up. I knew the answers to the questions, but they get you to doubt yourself by throwing in something you never heard of as one of the answers in a multiple choice question. Alot of the stainless steels were discussed in the course and were new metals for me, I have been working at a structural steel fabricator for 18 years and never had to deal with certain types of stainless steels (300 and 400 series). Questions were asked about metallurgy, grain structure, and such, that was all new to me as well. I recommend the CWI prep course in that it help introduce alot of new material that I have never been exposed to.
Hey, Good Luck in your test. Hope you do well. It will be another notch in your resume'.
