Ada's graduation ceremony is held twice a year, once in April and once in September. Generally, after the exam, you can leave school after making sure that all the courses have passed. If you are not sure whether you can pass all the courses, you'd better wait until your grades come down, because you may need to make up the exam. You can apply to send your diploma to you, but you need to pay some money, not much. If you have more questions, please add me qq. My Australian student group and I will help you. All Australian college students, please adopt.
