Not allowed. Although Mr. Shi Leipeng has a certain popularity and influence in the field of English education, the accuracy of the test questions about CET-4 and CET-6 is not reliable, and the behavior of betting on the test questions is an opportunistic behavior to a certain extent, while the test questions of CET-4 and CET-6 are random and diverse, and any form of prediction and betting can not accurately predict all the contents, so Shi Leipeng's prediction of CET-4 and CET-6 is not accurate. CET-4 and CET-6 generally refer to CET-4 and CET-6. CET-4 and CET-6 are large-scale standardized tests sponsored by the People's Republic of China and the Ministry of Education, and implemented by China People's Education Examinations Institute and the Ministry of Education (formerly the Examination Center of the Ministry of Education). They are national teaching examinations, and their purpose is to promote college English teaching in China.
