Andrew had found school quite more interesting since becoming a Tomorrow Person. It had mostly to do with the fact that Liz and TIM could make any subject interesting, from History to Maths to English. His teachers noticed; he was called upon more often and could practically lead discussions on the subjects.
It made the other boys look at him strangely, but he didn't mind. As a Tomorrow Person, he was different, and he liked that difference. He found that he enjoyed being around people who understood him.
And if it eventually got him into university, so much the better.
