When the time comes, you will apply to the local self-study examination institution for graduation with your grade certificate. They will give you a list for you to fill out, proving that you have passed all the subjects, and then they will let you contact the relevant tutor of the school you applied for. Then you should start writing an outline of your paper and show it to the teacher. After agreeing, I began to write specific papers. After you finish writing, you will be corrected by your tutor. When you finish your thesis defense, everything will be OK.
In short, the people in the study room will teach you after you have passed the exam.
