Hello, what you want to ask is whether the final paper was returned by the teacher for revision. Once the final paper is returned by the teacher, it will be revised. The purpose of the teacher's returning the revision opinions of the final paper is to help students improve their papers and improve their quality, instead of letting students revise them many times. Therefore, the teacher returned the final paper for revision. Finalization of the paper refers to the final revision and arrangement of the paper after it is completed, so that it meets the requirements of standardization, accuracy, completeness, clarity and conciseness, and finally forms the final version of the paper.
