Benci Belia EXAM!!!

Exam in 2.5 weeks and im very scared of failing. Luckly bm and bi on the first day but the next test is gonna be sejarah!!!. Studied abit on sejarah and in about 10 minits i surely fell asleep for real. Now my f***ing accounts teacher said that he's gonna come for real today and turns out he's not coming. Im very pissed coz he nvr come for about 1 month and now it's so late to get a new accounts teacher. I hope to get a new teacher that can be REALLY reliable.
