I just took the Magento certification exam at Magento Imagine today. I am proud to say that I passed. It was not easy however. If you are looking to take the test, here are a few quick tips to help you:
- Know the layout XML for Modules thoroughly
- Know the EAV module thoroughly
- Know Quote, Payment, and Order Classes and how they are utilized
- Know how to create admin interfaces and what classes help in this process.
Obviously, you should know this stuff as well as everything else they recommend in the study guide, but it's these things that they a) delve into deeper than I had thought, and b) they cover many things that are not covered in the Fundamentals of Magento Development course. I highly recommend you have been developing modules solidly in Magento for at least a year.
Also, beware of trick questions. Sometimes, they will throw you for a loop for items that are close, but not quite right.
Bottom line, know your stuff, study hard, and make sure you focus on Module development.
Look for that great badge on my site very soon!
