The Harvard website says “Scholarly articles, research, creative writing or other documents of which you are the primary author should be submitted in the Upload Materials section of the Applicant Status Portal.”
Does this mean that, unlike most other schools, I should submit my whole research paper? If I have multiple, should I submit more than one or is this excessive? Or should I simply submit abstracts?
Harvard Admissions Officers are likewise pressed for time. The more material you submit does NOT mean a reader will spend more time with your file. What they will do is skim. Do you want your essays and teacher recommendations skimmed as you sent in multiple research papers???
I would submit an abstract, not longer than one paragraph describing the research paper and how you materially participated in the project. If Harvard wants to read the full research paper they will email you and request a copy. Remember the adage in college admissions: The thicker the file the thicker the kid. You don’t want to be known as “the thick kid.” Less is more!
