We realised about 3am that our flat had been destroyed and despite being at a friend’s house, my sister couldn’t sleep, so she studied for the exam instead.

We had told her she didn’t have to sit the exam because of the extenuating circumstances, but she had studied so hard for it she was determined she was going to take it.

Her school had even contacted the exam board and told her she didn’t have to come in, but she wants to study chemistry at A-level. She said it went well, and my sister is a smart girl, so if she said it went well, it did.
