Yes, every year. Only those who have obtained primary or intermediate or advanced education in that year can be exempted from continuing education in that year and not participate. This depends on the requirements of each province. Some provinces do not participate, and they can make up for it in the second or third year. Sometimes, they don't give you a chance. If you don't make up for it, it will affect your taking the intermediate or advanced exam or the exam that requires you to show the certificate of continuing education. If you fail after joining, you can continue to answer questions.
