We had a maths lecturer who got us to buy their text book. Turns out the text book was just copy pasted sections from other maths textbooks in one book. Cost 30 quid, had the old page numbers and was therefore a confusing mess throughout.
My tutor then pointed me to a better maths textbook which was actually worth the money, shame I didn't know about that before!
