-I <span style="color:#ff0000;">have</span> (why not <i>had</i>?) a radio interview with British Sound <span style="color:#ff0000;">today</span> and it was just delayed by 70 <span style="color:#ff0000;">mins</span>. I will be able to get back to <span style="color:#ff0000;">campus</span> on time.<br/><br/>1. Why not <i>had</i>?<br/><br/>2. For the abbreviation of <i>minute</i>, is the <i>s</i> optional for a plural time?<br/><br/>3. Could <i>campus</i> be used without <i>the</i> apart from<i> on/off campus</i>?
