That means knowing the majority of (DCA) content is required because they test randomly on the many subjects available. Be aware too that experience requirements often exist because they've observed the average person and what is required. You can always push past that to succeed with the (DCA) but it may take some extra work.Practicing for an exam like the (DCA) can be a full-time job. In fact some exams are actually paid for by work because they are so intensive. Certification is not simple and takes immense work. It takes time, practice, and the right focus. We understand that because we have been in this industry for years and working in space full of less savory test prep sources.
