<p>Do you need to submit Part I and pay for the application before you can continue to part II? Is there even a part II? Where do I write down my EC's?</p>
<p>I think you can start Part II before you submit I, and yes, there is a Part II and a Part III. ECs and all that fun stuff in part 2.</p>
<p>Part III? U mean the app for need-based financial aid?</p>
<p>i myself worked on both parts I and II, and when i was done w/ both, i submitted part I, sent in the $, and then submitted part II</p>
