Barron's ACT Math and Science Workbook

The book covers math topics broken down by major subject (pre algebra, algebra, geometry, plane geometry, and trig I think). Within each subject it covers more specific things and has sample problems. There's a mini-test at the end of each section with about 10-15 questions on what was just covered. I didn't look at the science section at all so I don't know what's there. There is one math and one science practice test at the end. I think the questions and material covered were a lot harder than the other prep books I've used, including the Real ACT Guide. More on things like graphing trig functions, etc. that I don't think are really crucial for the ACT, at least not in the depth they go. It was good for picking out some harder problems but I don't think I would use this as my main math review book. Update: I like this book a bit better now that I've revisited it, after thinking the other review books were too easy. My biggest complaint now is that there is only one practice test. I think it would be much better if they made the book math only, and had 4-5 practice tests at the end (like McGraw Hill's does) instead of only one. I don't know if all of the content covered will actually be on the ACT, but it's a good book for those who want to err on the safe side by learning more.

We got the book really quick and in good condition. I am happy with it.
