He was right, the evaluation deadline is not that important, and he was a little irritated when another guy intruded into your conversation. Both incidents showed that he would like to spend time alone with you, and wanted to spend more time. I think he is interested in you, and you want to date somebody who is interested. At this age, you all care about "saving face", which leads to passive-ness. I bet he also thinks about you often, but not sure if you are really interested in him.
