Adult self-study exam is to take one subject and pay the certification fee for one subject. No tuition. Because it is a self-taught exam, you don't have to pay tuition fees. Of course, you can take the exam this year. If it is taught by a training center, it is generally necessary to pay someone else's teaching fee. If you don't pay it, they can't help it, because the self-study exam is managed by the local self-study exam, and the self-study exam doesn't need tuition. If you apply for the self-taught exam through the training center, your school status and exam subjects may be controlled by the center, and you may not be able to take the exam unless you hand it in. If you apply to the Education Bureau's Self-taught Examination Office, if the training center can't manage it, you can continue to take the examination.
