Am new to SCJP preparation. It would be great if somebody can give guidance regarding finding good source for exam dump / questions / practise tests etc., I am an OCP before, graduated 2004. I know the practise tests and questions makes a big deal while preparing cert exams.
from my knowledge the ultimate book and sample tests and exam are this
the authors are the developers of the SCJP exam.
And the scjp forum http://www.coderanch.com/forums/f-24/java-programmer-SCJP
I recommend this book http://www.amazon.com/SCJP-Certified-Programmer-Java-310-065/dp/0071591060/ref=sr_1_1?ie=UTF8&qid=1292010257&sr=8-1.
It contains all that you need to pass the exam including practise test. Also, if you want to try on simulators before taking the real one, I will recommend this site http://www.whizlabs.com/.
Note that I have used the mentioned materails to pass the exam on OCJP6 and I think it will help you a lot. :)
as above said, amazon.com is good site for scjp material,
to prepare for SCJP one should refer to the book kiethey serra and bets,
and you can try some onlline mock test, as per my knowledge following sites provide good mock test,
