Unreliable is a scam. Before signing up, our health manager said that all students can pass the 980 exam fee and then go to the scene, only to know that other schools don't have this fee, and the teacher asked me to teach me the 9000 fee before the exam. What's the point? Later, after the exam, we found that none of us had passed the exam because there were insiders in the school. I hope everyone will not be deceived.
