You are only as good as your application.

You have probably heard of students with perfect GPAs and eye-popping test scores who didn’t get in anywhere. You have probably also heard of students with subpar numbers who got in everywhere. What’s the difference? Their applications. Don’t let your application hold you back from getting in.

The fact of the matter is that schools don’t accept people. They accept applications. Your qualifications alone will not get you in. You need an exceptional application to match them. And our expert admissions assistance team will help you do just that.


Applications are not just forms to fill out.

Along with your standardized tests and list of extracurricular activities, you need to master the art of establishing an outstanding application. Applications, like poetry and essays, are a genre. Bridging the gap between who you are and how you appear on paper takes serious work.


The art of the application.

A great application starts long before pen meets paper. Even if you have the qualifications, it takes a lot of thought and work to be able to translate who you are and what you are about into an application package that rises to the top. And that’s why we’re here – to help you create a winning application that will get you from being considered to being admitted.
