<p>Are these supposed to be fairly straightforward? or creative?</p>
<p>Treat them as shorter essays. "My most meaningful activity is <strong><em>... I've done it since _</em></strong>... I like it because__.." would be really dull. That's not what they want. So I guess they are more creative than straightforward. Put as much effort into these as you would into the extended essay.</p>
