<p>Same with Intel STS. Do you have to be a senior, or can juniors enter these competitions as well?</p>
<p>I'm pretty sure you can enter Siemens. For some reason I remember a junior doing it last year. I don't know about the other.</p>
<p>You can enter siemens and ISEF fairs as a junior (I know people who have done well in both as juniors) but Intel STS is seniors-only.</p>
<p>Isn't it true that seniors only for individual projects? So you could enter as part of a team...if you're a junior or younger</p>
