By systematically analyzing students’ achievements in the Office advanced application course and the corresponding error prompts, key factors affecting performance are identified, and strategies for teaching improvement are proposed. The study is based on data collected from students’ electronic exam papers, including scores for each modules (Word, Excel, PPT) and error feedback for specific questions. Through statistical analysis of the score distribution and classification of error types, we found that some students have significant knowledge gaps and skill deficiencies in specific modules, especially Excel, which generally performs lower than the other two modules. In addition, the study also revealed some common error patterns that are closely related to teaching methods, learning resources availability, and study habits. Based on the above analysis results, this article puts forward several specific improvement suggestions, such as optimizing teaching content, increasing practical opportunities, and providing personalized learning support, in order to enhance the overall teaching effectiveness and students' practical operation ability. This study not only offers valuable insights for the teaching of Office advanced application, but also provides a reference framework for the design and implementation of related courses.
