### Chinese: 但知识点基本不变，并不代表考试题型单一、试题重复。
### English: But the knowledge points are basically unchanged, and do not mean that the exam is single and the test is repeated.
### Errors: There is a minor error at "points". There is a major error at "the exam is single and the test is repeated".

### Improved English: However, the unchanging basic knowledge points do not mean there can be single type or repetitive questions.
