I received a short message about the qualification exam on my mobile phone these days. Are you a liar? I said pay half the money first, and then pay after passing the exam.

Hello, this is obviously a lie. If it doesn't pass, will the money not be refunded? Even if you say you want to pay it back, you think the money will be returned to you when it reaches someone else.

Although I don't know what kind of exam you are talking about, many professional exams are now in the form of random questions from computer exams, and no one can guarantee to give you the original questions and answers. It is out of the question. Read more books and do more exercises by yourself. It's easy to work. Spend more time on your studies. There is no problem in passing the exam.

I hope I can help you and adopt it.
