I am a passive member of this Great site for the last 1 year... Gave my exam on 2nd April after 1 month of serious preparation & scored 72%..
I studied from RHE (mainly) & KM, I found KM to be much more descriptive than RHE, so I had to give much more efforts on KM... But when the exam was near I started to give JQ+ tests, I feel it's the mock exam's which made the difference...
I could get my weak point's & tried to fill the gaps...
My advice to the future wannabe's that JQ+ mock's are much more difficult than the actual exam so if y don't get high score in it the don't get discouraged... But Markus Green mocks are quite similar in difficulty level to the actual exam.
The main Exam is quite straight forward & most important they don't see how much y can mug up, they check ur understanding of the subject, but having said that I must admit that there were few tough questions also (in my case, I got few of them in AWT & Threads).
So Best of Luck, to all those who are going to appear for SCJP
