Analytics Software

Hi All

I'm looking for some advise on how to go about certification in OBIEE. According to information at education.oracle.com, we need to attend training courses before taking the Siebel Analytics Application Developer exam. Is there any change in the certification path where the course/training is not mandatory to take the exam. I would like to start at the beginner level certifications. Would really appreciate any help in this regard.

Thanks
