<p>I placed in Chemistry in ISEF and overall, I feel ISEF is like any other science fair, just 100 times more project and 10 times more interviews. Also, you know that you have to win the state science fair to qualify for Isef right? well at least in my state i had to...</p>
<p>If you go, I highly recommend that you review your project a couple of times and research some back ground information. For half of the interviews, you are asked to tell about the project but for other half they ask you specific questions. (some not about your project but about the field in general, so do research!!!) </p>
