contractions

Is it okay to use contractions in college app. essays?

<p>My english teacher advised not to because it isn't as "formal", but if you are using a dialouge in your essay, then anything goes. But I would stick to being safe and just write out the whole word.</p>

<p>They aren't necessary, so don't use them in your essays. I doubt they would even think much of it, but as a rule try not to.</p>

<p>Wow posted at like the same time. I used contractions in dialogue in my essays so I think that's okay to do.</p>
