My school has a system where you could only choose eligible books and each book had a pre-assigned amount of points it was worth based on reading level/pages/etc and you would have to take a quiz to make sure you read the book. So I did the opposite and I read 3 really big books worth 40pts each and only had to take 3 quizzes which for some reason were the same amount of questions as lower level books. Wasn’t enough to beat the kids that actually enjoyed reading and read a crap ton of books for fun, but at least I was able to get free tickets to 6 flags each year.
