How to Answer a Supplemental Essay in 150 Words or Less

A 150-word supplemental needs a different approach from a personal statement: direct, specific, and built for the constraint. Most short answers go wrong not because the writing is weak, but because they're written as though there were more room.

It helps to know what 150 words physically is. It's one paragraph. Depending on your sentence length, it's somewhere between six and nine sentences — about as long as this section and the one below it combined. That's the whole space, and you'll be making trade-offs inside it whether or not you plan for them.

Why scene-setting usually fails

At 650 words, a scene can breathe. At 150, a slow opening can consume half the answer before you've addressed the prompt. Get to the point faster — not because depth doesn't matter, but because every sentence needs a job.

The arithmetic is unforgiving. A three-sentence opening scene runs 45 to 60 words, which is a third of your answer spent before the reader learns what you're answering. And a reader who doesn't yet know where the answer is going has no way to tell which details in your scene matter, so the setup does less work here than the same setup would do in a longer essay.

This doesn't mean concrete detail is out. It means the detail arrives after the reader knows what it's evidence for.

Answer the question first.

State your real answer in the first sentence or two. Then spend the remaining space on one concrete piece of evidence.

A workable budget for 150 words is something like 25 words of answer, 100 words of evidence, and whatever's left over. That leaves room for one thing developed properly, which is about the most a short answer can hold.

One thing not to spend words on is restating the prompt. "There are many reasons I'm drawn to studying linguistics" tells the reader only that you read the question, and they have the question in front of them. Start with your answer to it.

One specific detail beats three generic ones.

One memory, class, project, or conversation developed with an actual detail is more convincing than three abstract reasons.

The difference shows up in a single line. "I've always been fascinated by how language changes over time" is a reason three thousand other applicants could give. "I spent a summer transcribing my grandmother's Tagalog for a family recipe archive and kept hitting words with no clean English equivalent" belongs to one person, and it costs about the same number of words.

That's the part worth noticing: specificity isn't more expensive than generality. It usually runs the same length and does more, which makes it the highest-leverage change available at this size.

Cut anything another applicant could write.

It's worth asking of every sentence: could a different student applying to a different school write this exact line? If so, cut it, or make it unmistakably yours.

Interchangeable sentences cluster in predictable places. They're in the opening, where writers warm up. They're in the closing, where writers summarize. They're in transitions, and they're anywhere a superlative appears — amazing, incredible, perfect fit, passionate about. Those are the first places to look when you're over the limit.

What to cut when you're 40 words over

Almost everyone drafts long, and cutting is where short answers actually get written. In rough order of what to remove first:

Anything restating the prompt
Hedges — I think, I believe, sort of, in a way, one of the things that
Adverbs, most of which are doing less than the verb already did
The closing summary sentence
Your second example, so the first one can be developed properly
Setup explaining why the thing you're about to say matters

What shouldn't go: the concrete nouns, the specific numbers, the named things. Those are the parts only you could have written. Cutting them is how a draft ends up under the limit and interchangeable at the same time, which is the worst of both outcomes.

Don't force a miniature personal statement.

A short answer doesn't need a narrative arc, a clever opening, or a callback ending. It needs to answer what was asked, with specificity.

The hook problem takes care of itself here. In a personal statement you're competing for a reader's attention from a standing start. In a supplemental, the reader arrived with a question they want answered, and answering it directly is the thing that holds them.

It's also fine to end on your last piece of evidence. A wrap-up sentence that tells the reader what they just read costs 15 or 20 words and adds nothing they didn't already have — at this length, more than a tenth of the answer spent summarizing itself.
