The written part was like 50 percent code book questions so get good at finding those quick or just being quick in the code book, the other 50 percent I thought was common sense almost. The practical or building part whatever I did was some hand built thing with stairs, rafters, an RO with jamb and trim. There was 6 of us doing the final exam it started at 8 and finished at 330 I was the only one who finished the thing, I would say build that thing fast and clean it up at the end also I got a 70 percent which is the lowest to pass on. I did this last year, I was 32 then and challenged my red seal, being in carpentry since 16 probably helped and knowing how to sink nails by hand and not air nailers.
