Later in the novel, the narrator's father gives two reasons to justify why his son failed the exam. What are the two reasons?

From the text:

You can see the cross I’ve got to bear for yourself. What’s more, my dear brother, do you know why he failed his exams? Shall I tell you? Women. I’ll wager you he’s done nothing but lay women the whole year he’s been in the city. He drinks , too. He hasn’t opened a book since he got back from Kala; he’s spent his whole time running around the countryside drinking, or chasing the girls, like a dog on heat. What a worthless son!
