Normally when you see a link for ESSAYS ON THE INTERNET, it’s a money-making scheme to sell desperate students poorly written essays.
The Concord Review, though, publishes the top research papers from around the world as a showcase for colleges/future employers to look at. If you want to submit your essay, here are the guidelines. I will say this, though: there is a fee associated with submissions and the essays all deal with history.
I think the site is great to show off examples of well-written student work and definitely being published here would make for a nice addition to your college application.
