Evening all, DD sat RE in a room near a toilet so she could go if she felt ill. She said it's a bit of a blur as she felt woozy but she did it.
She's now revising for tomorrow's Chemisry, not 100% well but hasn't been sick since about midday (although she hasn't eaten).
On a bright note, she's been a lot nicer as she seems to have stopped stressing, possibly because she now accepts she can only do what she can do. :)
