Today I cleared the SCWCD 1.4 exam with 84%. The real exam appears to be much simple than what you expect after going through HFSJ. There were a couple of spelling mistakes in the real exam, which puts you in doubt while answering.
I would suggest that HFSJ is the best book in the market to prepare for the exam. It is fun while going through such a book.
My heartfelt thaks to the authorial team for coming out with this wonderful book. Hope they keep up the good work and come out with more such books on a variety of topics.
