It doesn't answer some of the most frequently asked questions about these certifications (at least here on the Ranch) such as do the questions tell how many option have to be selected, are there any drag and drop style questions. (The answers to these are Yes and No respectively, btw.)
Even though the FAQs at Oracle.com lack completeness, they score over the FAQ at JavaRanch in terms of the credibilty of the answers. The questions there would be answered by the folks at Oracle themselves, armed with 'insider's information' on certification process. Their responses wouldn't be 'personal opinions', which would make them credible.
This is not to state that the responses here are any less good. Both experts and newcomers answer questions here. Ranchers benefit from the experience of experts. However, answers by newcomers can be based on guessing work or assumptions, which can be misleading or incomplete.
