If you have already registered for the enrolled agent exam and have not bothered to study or practice for the exam, then you should probably reschedule your exam date. Many accountants or tax professionals naively believe that they can pass the enrolled agent exam without preparing. And while some tax professionals will be able to pass one or more of the enrolled agent exam sections, it is nearly impossible to pass all three sections of the exam. While the enrolled agent exam is a multiple choice exam, the questions can be tricky and if you haven't practiced for the exam, you are likely to get them wrong.
Additionally, the enrolled agent exam tests your knowledge of recent changes to the tax code, so if you haven't prepared and studied all of the changes, the chances of you passing the exam are pretty slim. Luckily for tax professionals and non-tax professionals, there are a number of enrolled agent courses, which will help you prepare to take the exam. The great thing about studying for the exam is many of the questions from the practice exams will appear on the actual exam and you will know the correct answer to them. Not only that, but the quicker you can answer the questions correctly, the more time you will have near the end of the exam to go back and answer any questions you were unsure of or that you didn't answer. It is always recommended that you answer the easy questions and leave the harder questions towards the end of the exam since it is a timed exam. The exam does not weight the questions, so the more questions you are able to answer correctly the better. Though, if you have studied and prepared for the exam, you will find it pretty easy and you will already know the answers to many of the questions, since you will have seen the same questions or very similar questions, from your practice tests.
