Marcelo can you be more clear what you want to ask. There are no questions on testing in SCJP. If you want a list of mock exams, then you can find it in the SCJP FAQ (the link is in my signature)...
In the SCJP FAQ there are some comercially available products, from that list are there an evaluation/review of those products? Are they really objective oriented? reliable? I am considering getting one but I'd like to know if anybody in the forum have any experience with it!
