In Nothing But the Truth by Avi, Philip Malloy is not on the track team because in order to be on any team at school, students must have an academic average in each subject above a "D" grade. Philip has a D in English due to his laziness and his dislike for his teacher, Miss Narwin.
Philip had not realized that his grades had to be better to run track, so he tries to get the coach to see that it's not his fault. The coach, however, has to follow the school rules, so he tells Philip that Miss Narwin might be willing to change the grade if Philip asks her for extra work. Philip, instead, ends up causing all kinds of problems for Miss Narwin, the school, and himself.
