<p>Can I submit the housing application even if I'm not 100% sure that I'll go to UCSD??</p>
<p>Yes you can and you should. It costs you nothing, if you do decide to attend UCSD the dorm assignment is based on your priority date and requested housing arrangement. To quote Nike, "Just Do It!"</p>
<p>yes ... they even say so on the housing form, why are you questioning that? if it doesn't involve money (and it doesn't), just cover all your bases.</p>
