Do I need to come in next week?

No, it's only the first week of term. You'll only miss the introductions to all of your second year units!! Was I this bad at that age? Probably!! :o)

I'm on holiday after we come back

One of my returners has booked a fortnight's holiday during the second and third weeks of term. Genius! He'll get off to a cracking start to a year of panicked catch-up.
