Proofreading and editing an essay may seem like boring work, but if you approach it in an organized way, everything becomes easy. Don't forget that there's no need to rush things; it's better to edit systematically.
How to do it:
When writing an essay for business school, always leave time for editing. Pay attention to the terms of the assignment. If the essay has to be no more or no less than a certain number of words, keep that in mind. For more complex essays, it is advisable to write an outline first. When editing, refer to the outline - then you will know for sure that you have covered all the points. Read out slowly: an error is easiest to "lose" if you read too quickly.
