@Anemone_Wolfy I'm about to kill my math teacher.
I just got back from school. We had a math exam. She gave us a few tasks from the book that we could use to study. I used those tasks, I understand them and I could most likely use them now.
NONE of those were on the exam!
Instead there were questions about one thing she explained to us for like fifteen minuets at the end of class, gave us no tasks for during class nor to study and then expects us to get it right.
Of course there were other questions on the exam as well and some of them were okay but a few, I swear we didn't talk about them in class.
And its not just me, its my whole class and others from my year too.
