Which issue should be corrected prior to the proofreading stag?

Prior to the proofreading stage, issues related to content organization and structure should be corrected. This includes ensuring that the overall flow of ideas is logical, that paragraphs are well-developed and coherent, and that the thesis or main argument is clearly articulated. Additionally, any major factual inaccuracies or inconsistencies should be addressed, as these can significantly impact the clarity and effectiveness of the final document. Correcting these issues early allows proofreading to focus on surface-level errors like grammar and punctuation.
