I too trying hard for this Weblogic Admin certification.
Here is my Road map for certification.
I believe, key success for your Administrator certification - as many scenarios you soleve that much real time experience we get to move forward for a great success.
1. URL from BEA to lean about certification http://www.bea.com
2. Download all PDF files from above URL and try to cover them all
3. Practice Realtime scenarios and problems
4. Mock exams, found one from BEA website itself. But come accross couple of other PAID websites which gives all that training material.
Please add your comments, suggestions, URL's into this so we can crack it easy.
