I just passed the SCBCD yesterday with a 95%, so I thought I'd just tack on to this thread ... The #1 factor for me was my Head First book. I started it about 3 weeks ago with no prior EJB experience, and this book was enough to prepare me very well. I read it three times, once thoroughly and twice hopping around to where I wanted to focus. I also used ejbcertificate.com -- I love that website! I wish the questions weren't recycled quite so often, but it was still a great resource for trying different tests and finding my weak areas.
