Supplemental Essays: How to Write the Why-This-College Answer

Applies toπŸ‡ΊπŸ‡Έ

The 650-word personal essay is written once and read by every college on your list. The supplements are written for one college each, read by people who know that college intimately, and are where most applications quietly go flat. They are also, for that reason, the easiest place to gain ground.

The swap test

Take your finished why-this-college essay, replace the college name with a different one, and read it again. If it still makes sense, it is not finished.

Almost every first draft fails this test. Excellent faculty. A vibrant and diverse community. World-class research opportunities. A campus that felt like home the moment I visited. Every one of those sentences is true of two hundred institutions, which is precisely why none of them persuades anybody.

An admissions officer reading supplements for their own college can tell within a sentence or two whether you have actually looked. They are not offended by a generic answer. They simply learn nothing from it, and it becomes one more application with nothing distinguishing it.

What specificity actually looks like

Specific does not mean flattering, and it does not mean reciting facts from the website. Rankings, founding dates, the student-to-faculty ratio and the number of clubs are all things the college already knows about itself.

What counts is a connection between something concrete there and something concrete about you:

  • A named course, and why it follows from something you have already studied or built
  • A professor whose actual research overlaps a question you care about β€” having read something of theirs, not just their title
  • A structural feature that matches how you want to work: an open curriculum, a co-op programme, a required thesis, a particular lab or studio
  • A programme that would let you combine two interests that are usually separated

Two sentences of that beat a paragraph of admiration. The test is whether the sentence could have been written by an applicant who had not done the reading.

Do the research efficiently

If you are applying to ten colleges, that is potentially thirty supplements, and doing it well is a time-management problem more than a writing problem.

Work from the course catalogue rather than the admissions pages. The catalogue lists actual classes, which is where the specific material is; the admissions site is marketing, which is where everyone else is getting their sentences. Twenty minutes per college in the catalogue and the faculty directory yields more usable detail than an afternoon on the brochure.

Keep a note per college of three concrete things and why each connects to you. That note is the supplement. The writing after that is fast.

The other supplement types

Why this major. The trap is a origin story β€” I have loved biology since I was small. Better is the current version: what specifically in the subject holds your attention now, and what question you would want to spend four years near.

The community essay. Community does not have to mean ethnicity, nationality or religion, though it can. It can be a team, a workplace, an online group, a family role. What is being assessed is how you behave among other people, not which category you belong to.

The short-answer and quirky prompts β€” a favourite word, what you would teach, the hundred-word list. These reward genuine specificity and personality, and they are the one place where being slightly odd is an advantage. The safe answer is the wasted answer.

The extracurricular elaboration, usually 150 words on one activity. Do not summarise it. Pick one moment inside it and write about that, because the summary is already on the activities list.

Word limits are hard limits

A 150-word supplement is not a shortened 650-word essay. It has no room for an introduction, a scene-setting paragraph, or a conclusion restating the point. Start on the substance in the first sentence and stop when it is made.

The most common failure in short supplements is spending forty words arriving. "Throughout my academic journey, I have consistently sought opportunities that challenge me" is a sentence that could be deleted from any essay ever written without loss.
