Now the exams have begun again

It is very simple either
1 the teacher hates you
2 the teacher is making the course to hard
OR
3 you dumb

That is why I read over my notes the night before, then went to sleep. You can't think straight when you are sleep deprived.

mmeeeeEEEEEE

Math is not about reading books, it is about solving problems. Questions?!

It isn't about how much you studied. It's about what you wrote. They're teachers not psychics, so they can only grade what you write, not what you meant to write.
