Hi Friends, I am a SCJP and planning to get SCWCD and SCBCD certified. Please provide me useful information/sites that will be helpful for preparation. All suggestions helpful for prepartion are greatly appreciated. Especially which book(s) I have to use, and roughly how much time I need to spend for SCWCD and SCBCD preparation. Thanks for your time and help. PS: please excuse me if this is not the right forum for this post.
