What is the narrator point of view in the novel, Notes of a Crocodile?

An anonymous first-person narrator tells the story of her college years, which is the story of the novel, save for the interspersed third-person crocodile scenes. At the end of the novel, another first-person character, Derek Jarman, voices these crocodile scenes as he films the crocodile. The tense primarily remains in the past throughout the novel, complementing the content as a story of her college memories; however, the narrator shifts to the present when commenting about certain memories in hindsight.
