It is terrible with Science. Uses bad language. And wants very specific wrong answers. It will ask if something is clearly true, or clearly false and it will have the answer as something that is neither. It asks when something will cross a scientific threshold, asking for a specific year. And then rounds past the answer. I was forced to buy this book as part of my online course. It should still be in editing. I have found multiple wrong answers in the homework, quizzes and tests generated by the book. I ignored it at first. But mid semester this is ridiculous. Everytime I find an error I go right to office hours and make them email the writers and editors of the book. They should volunteer a refund to every student who has had to purchase this thing through the selection of a course. It has one nice feature "the help me solve this." But even then it will lead you to a wrong answer. You don't ask what year something crosses a Scientific threshold and then decide the correct answer is the year after
