Of course. Although you missed two courses in the self-study exam, you can still apply for it next time. However, I suggest that you carefully consider your study and schedule before the exam to ensure that you have enough time and energy to prepare for the exam and take the exam. At the same time, you can also consult the relevant self-study institutions or teachers to get more suggestions and guidance to help you better prepare for and cope with the exam. Remember to read the relevant registration regulations and examination requirements carefully when applying for the exam to avoid situations that do not meet the requirements. Good luck in the exam!
