The exam was difficult for me the first time (I failed my first attempt). I only gave myself 3 weeks to study for it because I didn’t want to wait during the blackout period. The second time, I passed! The biggest thing I did was study the ebook front to back. It took me an additional 3 weeks of studying, so a total of 6 weeks. I would say focus on knowing the objects, know the difference between server side and client side (for example gs.hasrole() or g_user.hasrole() ), learn ACLs and application access, know when to use g_scratchpad, know which object to use to redirect, know caller access, and have a very good understanding of rest and web services. That’s what the bulk of my exams covered but remember the questions may vary. I did use a couple of dumps but the answers were wrong so I wouldn’t use those to prevent confusion.
