I just pass the exam of SCWD,then next I wanna take the examination of SCJA,but I know little about it.I am poor,so I never buy any materials or take any course on SCJP and SCWD.What can do is to select free information from the internet.But now,I search materials on SCJA for a long time,and didn't find anything useful.So I need help: 1.How hard the exam is? 2.How do I prepare it? 3.Could u give me some resource on it?
