Would you happily spend 5 separate hours in 5 separate classrooms, at less than 1 m from over 30 teenagers, every day for a week, without proper ventilation, moving through corridors jam packed with hundreds of teenagers in between?
You could try to help them with their work individually, if you would like to, as well.
I'd recommend Greater Manchester, or Leicester for preference.
It's very nice of you to say you'll spend a bit of tomorrow with 30 in your own selected area, but that isn't the job...
