If you want to give someone a grade or score in an Engpsh composition, you can say something pke:
"I would give your composition a (grade/score) of (number) out of (total number possible). I think your use of language and structure was (strong/weak), and your ideas were (well-developed/not as developed). Overall, I think you did a (good/great/poor) job on this assignment."
You can also use specific words or phrases to describe different aspects of the composition, such as "clear and concise" for language, "well-organized" for structure, and "thought-provoking" for ideas.
It's important to be specific and detailed in your evaluation, as this will help the person understand what they did well and what they can improve on in future compositions. It's also a good idea to provide constructive feedback, rather than just psting criticisms, so that the person has specific suggestions for how to improve their work.
