Query: Pricey, but if you are looking to learn calculus, this is A+

After taking differential calculus, integral calculus, and elementary differential equations, I took a year off of college. Then when I came back, I had forgotten alot of things concerning those courses. Well, I bought this book because it had the most pages and seemed to cover the most information. Well, it was a good buy! It covered ALL of the material that I had covered in those 3 previous courses. It was a great book for refreshing my memory. This would also be a great book for learning calc for the first time also.
