<p>Is it possible to use both common app. and College's own app.?
I mean I want to use common app. for recommendation part and College's own app. for other informations (e.g. personal information, essays.....)</p>
<p>I wouldn't recommend it.</p>
<p>Don't do it- pick one or the other. Because the common app can be used for other colleges too, I suggest just using that, and the college will treat it as if it were its own (in case that is worrying you)</p>
