When to Expect the Worst

When you ask your teacher what the homework is, you're always crossing your fingers for 2 things.
Thing #1
There will be NO HOMEWORK!
(And failing that...)
Thing #2
The homework will not be to REVISE!
Yes, you must be prepared to expect the worst when your teacher tells you your homework is to revise. It means days...weeks...months...of looking over your text books and exercise books, cramming all that knowledge that you've already forgotten into your head again, and for what? How will they reward you for your efforts?
At best, with approximately five days of regurgitating all that stuff that, since the beginning of the year, has gone in one ear and out the other.
Is that fair?
I tell you now, it is not.
And then the teacher stream you, trying to turn you against each other by calling some people clever, and others..."I'm sorry, you're in the bottom group." They assume that because you can't remember something you learned 9 MONTHS AGO, you're not particularly clever.
No, exams don't measure how clever you are. They measure how much you can be bothered to revise. It's a good job I do revise, or I'd score a round, 0%.
