Aspirants can utilize feedback from writing practices to improve their responses in UPSC by first identifying common areas of weakness. Constructive criticism highlights specific aspects such as coherence, argument strength, and adherence to the question asked. Regularly implementing this feedback allows candidates to refine their writing style and develop clearer, more persuasive responses. Incorporating peer reviews can also provide diverse perspectives and suggestions for improvement. Ultimately, using feedback effectively leads to enhanced writing skills, crucial for both Mains exams and comprehensive answer writing.
