The difficulty of publishing SCI papers depends on many factors. In some professional fields, such as biochemistry and environmental materials, it is relatively easy to publish SCI papers, because there are a large number of journals in this field, which are easy to publish. However, in some other majors, especially in areas where the number of top journals is limited, publishing SCI papers may be more challenging. For master students, the difficulty of publishing SCI papers also varies according to personal circumstances and the degree of support from tutors. The guidance and support of a good tutor can greatly reduce the difficulty of publishing SCI papers. In some cases, master students may need to make full preparations to publish SCI papers, which is of great significance to their academic and professional careers. Therefore, the difficulty of publishing SCI papers depends on the specific situation, but hard study and preparation are still the key.
