There is a certain difference in the difficulty of the exam between the single move and the comprehensive assessment. In general, the difficulty of the exam for single recruitment is relatively low, while the difficulty of the exam for comprehensive assessment is relatively high.
The single-enrollment examination mainly focuses on the examination of basic knowledge, the difficulty is relatively low, and the acceptance rate of the single-enrollment examination is relatively high, generally above 50%, and even as high as more than 80% in some regions. Therefore, for some students with a weak foundation, single recruitment is a relatively easy way to go on to higher education.
In contrast, the comprehensive assessment pays more attention to the comprehensive quality and professional ability of students, and the examination is relatively difficult. The content of the comprehensive assessment is more complex, not only to examine the academic level of students, but also to conduct interviews, practical operations and other aspects.
In addition, the number of students admitted to the comprehensive evaluation is relatively small, and the acceptance rate is relatively low, generally below 20%, and even less than 10% in some areas.
Therefore, for some students with a solid foundation and high comprehensive quality, comprehensive assessment is a more challenging way to further education.
It should be noted that there may be differences in the difficulty of individual recruitment and comprehensive assessment exams in different regions, so the specific difficulty of the exam needs to be evaluated in combination with local conditions.
