I typically write my own notes and not correct the resident or medical student notes, and have noticed they sometimes copy mine!!
You should just ask the attending for feedback on how to improve. As attendings, we write in a certain way because of need to be compliant with best practice guidelines, clinical strategic goals, coding and billing. The coders and chart reviewers for quality measures look for key words (hate this!) that you have to include in your progress notes. For coding and billing, for example, urosepsis is not accepted but UTI with sepsis is; malnourishment is not but malnutrition is, etc.
Finally, you will notice differences in styles and what one attending likes will be different from another, and copying one attending's style may cause you to be criticized by another. This will continue until you are an attending..... and you will then do the same to the MS and residents!
