In order to get the Symfony certification, and to be prepared to it, you have few options: train by yourself, get a training on sensiolabs or train by doing tests.
Thats what we prupose here, linked to the elements shown by the certification page, we grouped questions to be sure to master every single page on the symfony documentation.
