I have similar question, because I am studying for SCWCD 1.4 and I am thinking about doing SCBCD. Whizlabs has a buy 2 get third free exam simulator offer. So I am thinking of buing that, but then I have to commit to which exams to do. I studied first for SCWCD 1.3 and I discovered that there are big differences with 1.4, so if that is also the case with SCBCD i have a big problem. Any suggestions?
