Many students rely solely on the questions and answers provided by the tuition providers. Which should be the third step of your planning and not the first one. First step is to go through the official publications and guides and make a detail summary of what is involved in the certification exam. Once you have the summary, your life would be much easier.
Second step is to highlight the areas you are going to cover. You do not need to cover A to Z to pass the certification exams.
