Commonapp QUESTIONS!

<li><p>If I worked at a research company over the summer, do I need to get a letter from my boss at that company to add it to the Commonapp so they don't think I'm BSing? If so, where would I put it? (do i make copies of it and mail it to each school?)</p></li>
<li><p>The Commonapp lets you only allow a certain number of ec's. Since I have alot that I want to add (different leadership positions, alot of volunteering, different work places etc.) where do I the rest? Do i make an individual resume on word and attach it somewhere? </p></li>

<p>Please all advice is needed!
