<p>I wouldn’t say that Ghastn. A lot of people I know (myself included) didn’t take 218, for instance. I know some who didn’t take 215 or 217, though that’s less common (and many IMO medalists did take them). </p>
<p>Bottom line is that they won’t stop you from trying to take anything, but you should at least take 215/217 for a few weeks. If you find you are very well prepared then you can drop.</p>
