College students who are able to compile good graduate essays are in a position to do so even after they leave college. They would have completed several academic assignments on different subjects, basically developing their own style of writing. Eventually, they achieve a level that distinguishes them from the rest in terms of unique style of writing, ability to comprehend and present detailed information about a topic, and using vocabulary that establishes them as experts in a particular field. Compiling coursework material, term work, and practice essays is the established way that makes it possible. Students begin by writing descriptive student essays in school. The first competitive essay would probably be the college application essay. It would literally decide whether they get admission to a college of their choice. To pass out of grad school, they would need to submit a grad school essay as part of the final submission process. If they are to qualify as professionals in a subject when they leave college, they need to become subject matter experts. Compiling several essays on relevant topics would establish them as such.
