5 Mistakes to Avoid in Your Common Application

The Common Application makes it possible to apply to dozens of schools with a single form — but that convenience also raises the margin for careless mistakes. After reviewing hundreds of student files, we keep seeing the same patterns.

First: generic personal essays. A main essay written to please every school ends up saying nothing specific to any of them, and admissions committees notice immediately. Second: a quantity-over-quality activities list. Fifteen shallow club memberships are less compelling than two activities where you actually led something.

Third, waiting too long to request recommendation letters. Give your teachers at least six weeks so they can write something thoughtful, not rushed. Fourth: copy-pasting the same supplemental essay across schools without tailoring it — admissions readers spot this instantly.

Finally, skipping the final proofread. A sentence that mentions the wrong university name, or a section left half-finished, can undercut months of preparation. In our process, every file gets a line-by-line review from at least two consultants before it's submitted.

The good news: every one of these mistakes is preventable. The right timeline, the right feedback loop, and a second set of experienced eyes are usually all it takes for your file to reflect your real potential.
