<p>How quickly do the first couple of NSC dates fill up? </p>
<p>Very quickly last year. I recommend you register for your NSC the day (or even minute) the NSC registration opens. This was Feb 1st last year. Within a few hours the first session was full. </p>
<p>They do fill up quickly, and this year the registration has already opened up. It is part of your admission acceptance. Registered my D for the second session in June and as of Saturday afternoon it was already full and unavailable. I would log in a register as soon as you can.</p>
