Foolestroupe,

I had a book like that once in a database class I was taking. the course book was so bad that it was unreadable. There were even sentences without a verb. I'd read them over and over again but still couldn't understand them.

When I was teaching computer science, my students were most upset when they lost marks because of their bad spelling. I used to tell them, 'When you leave here you will be getting a job and you boss will care about your spelling AND the compiler won't work unless you get it right'
