First and foremost, be honest. College admissions boards want to know who you are; not some version of yourself that you’ve entirely made up. Don’t be tempted to make something up to make yourself seem more appealing. Admissions directors have seen it all and can spot a fake from a million miles away, so keep your answers true to life.
Find a happy medium. Don’t be too stiff or formal, but don’t take it to the other extreme, either. Your admissions essay needs to show you as someone who is ready to be a serious student and who will perform well upon admittance. Avoid using overly casual language.
Find a fresh set of eyes. Once you’ve completed your essay, find someone else to read it for you. Have them read the prompt several times to understand what to look for in your essay and then let them read it. They’ll be better at picking out mistakes or awkward sentences than you will be after staring at it for hours. You can be your own set of fresh eyes, too. Once you’re finished, put the essay away for several days, or even as long as a week. Come back to it later and read it again. Does it make sense? Is it an accurate representation of who you are?
Most importantly, don’t forget to breathe. College applications are intimidating, but approach them with a level head and clear thinking and you’ll find that you really know what to say after all.
