Good point.fool said:Why does the teacher need a book with the answers?
Don't they know the answers?
What's the big deal if a student has a book with the answers?
They still have to pass the test, better they have the right answers memorized insted of the wrong ones.
I think this is entirely the text book Mafia at work. We were working with a retired teacher that was trying to become an internet entrepreneur. He created his website and had his business plan and our company created the back-end database while talks were ongoing with suppliers. The textbook businesses was the backbone. But all talks broke down. Those #(*$#@^$ unreasonable people at the textbook companies have ridiculous demands. I'm telling you, something's rotten in Denmark.
