The new version of EJB exam is more focused and tougher than previous ones. You have to spend considerable time preparing for this certification (EJB 3.1). However, it does worth it as the new exam will be much recognised int the IT market. Shall you decide to go for SCBCD 5 please make sure it is as soon as possible for, Oracle might retire it soon. My advice, in case you have enough free time, is to go for the new exam. First, check the new exam requirements and find a link for stuy resources in this forum.
