I haven't passed the exam for three months, and it's getting harder and harder. Personally, I think you are naive if you make money by taking exams. (As I thought before) Actually, it's just a matter of circling money. It's useless! It's no use! You can get questions if you have connections. Luck is not important. The pass rate in Shenzhen is at most 10%. You are free to take exams and have fun. The examiner can't work out the problem. Eight minutes, not daring to demonstrate once, wasting money.
