Yes, be proud! About 1/3 of applicants are offered a secondary. About 1/3 of those people are offered an interview, and about 1/2 of those interviewed are ultimately accepted.
I never was able to get a typeable .pdf version, so I used the word document that they made available. It was designed with fields so that you can type right in and the resulting printed app looks almost as nice as the pdf.
I don't know if you are aware, but you are also allowed/encouraged to attach 2 pages of information about extracurricular activities (this is written in the secondary app if you look hard enough). At my interview, they handed us an "update page" and asked us to list what activities we were currently involved in. One of the admissions office staff said this was because "not everyone submitted information about activities." So it seems like they do look at and consider this extra information...might be worth including.
GOOD LUCK and congrats!!
