The other characters are cute, if a little stereotypical. I enjoyed Noah the most and was amused by his constant yearning to be expelled from the Academy. Chloe was also a cute character, but I felt the romantic element a little unnecessary and distracting.
I wasn't a big fan of the alternating narrative. Perhaps if it had been less random and had a little more development among fewer characters, I would have enjoyed it more. I also noticed an odd undercurrent of public school bashing. Admittedly, as a Canadian, I am not fluent in the issues plaguing the American school system, however, as a teacher, I felt a little insulted. We do the best we can with what we are given and I felt that the novel wasn't giving that process credit.
I can see this book appealing to boys (as most of Gordon Korman's books do) and being an enjoyable read for those reluctant readers.
