I am impressed by the dedication and commitment of many students and I was struck by one particular example yesterday. I had a tutorial yesterday evening and all the students who attended were very engaged and this is impressive in itself as they have busy lives and online tutorials are useful but not always easy ways for students to study as they require a great deal of concentration. One student joined the tutorial from China and he said it was 3 am there and he had especially set his alarm to wake up for it. He only used the textbox function rather than the microphone as his wife was sleeping in the next room (his choice seemed reasonable in the circumstances). He made a very useful contribution despite having only just woken up.
