Attend the Front-End Developer training. Attending training is not required before you sit for the exam, but much of the exam material is based on concepts covered in training.
Review the additional source material. Liferay Developer Network is an amazing complementary source of information for the exam. Pay particular attention to the topics included in the Front-End Developer training.
Practice. Some of the topics covered on the exam require the kind of knowledge that comes from real, hands-on experience developing for the Liferay Platform. If you have attended a Front-End Developer training, be sure you've completed and reviewed all of the exercises presented during class, even the bonus exercises. If you haven't attended the training, spend some time developing Themes, Layouts, and Templates that leverage the features described in the exam topics. It would also be helpful to review Liferay’s source code to ensure you're familiar with Liferay's best practices.
