The gap is not big. There is little difference between the scores of internal audit and external audit, because both internal audit and external audit are important links in evaluating papers, but the evaluation criteria and emphasis may be different. Internal audit is usually evaluated by experts or professors in the same field, who may pay more attention to the academic and innovative nature of the paper, as well as its internal logic and structure. External audit is evaluated by experts in other fields or industries, who may pay more attention to the practicality and application value of the paper and whether the paper meets the general standards and norms in this field. So there is not much difference in scores.
