I'm also wondering about that. I just went to the exams trying my luck and didn't expect I can get in at all. But then a teacher got interested in me at the initial exams. Later he kept contacting me and gave me instructions for free. When the exam result came out, I didn't go check it out. It was the teacher that called me to inform me about it. I didn't believe it at the time. After the third round of exams, I started to prepare seriously. Even though I didn't expect too much, I still passed. Honestly, I'm quite surprised.
