Several people asked me for advice about the @symfony certification, therefore here they are!

1/6
- Review the Symfony documentation with one or two other developers and ask questions to each other. Challenging point of views helps a lot to have a clearer understanding.
2/6
- Read the source code of Symfony to truly understand what's happening inside. Obviously, there is no need to know by heart all the Symfony's source code, but use it to lighten some tricky points.
3/6
- Code! Create a Symfony scratch project and try every feature that you do not truly understand. In that way, you can practice the main workflow and edge cases. You'll understand deeper these features.
4/6
- You don't need to know everything by heart (indeed you'll never be able to retain the whole Symfony documentation). You better have to understand Symfony's framework and components philosophy. In that way, you'll even be able to guess successfully some answers!
6/6
- If you can afford it as well, you can also take advantage of the wonderful lessons of @SymfonyCasts ( https://symfonycasts.com/ ) which will help you to understand either basics and details about almost every component.
