Wen Jing has an interview class, but there is no charge. Wen Jing emphasized that it costs nothing to train students! For example, for four days and four nights, the tuition fees of various training institutions are more than 2,000 yuan. No matter whether you pass the exam or not, you have to pay more than 2000 yuan for these four days and four nights. However, according to Wenjing's practice this year, if you fail the exam, Wenjing won't charge you a penny. Only by passing the exam will they charge you more than 2000 yuan. Compare yourself and you will know which is the most cost-effective!
