I have finally cleared the SCWCD. I am really thankful to the ranchers and the authors of the HFSJ. Preparing from this book for the exam was the best bet.Though I was not an active rancher but I was regularly in track of all the posts from others and the useful tips.
My score was just 76%. The only pitfall to the comparitively low score I got was lack of enough practice on all the sections given in the book HFSJ. The real exam is very simple as compared to the mock exam in the book and the time is ample enough.
