The Application Process

Hi,
I've been filling my apps and I noticed that there is going to be a lot of inevitable repetition in my app. I mention the most important of them in my essays, then in my resume and then in the activities/achievements sections of the application itself.

Is that fine ?

In case of limited achievements, as in my case, is there any other way to avoid repetition ?

Will it create any negative impression ?

Please let me know the answer to these questions.

Thanks Jon. Word by word repetitions should be avoided is a good takeaway. Thanks.
