Hello,
That book in your link is actually not the "Big Kaplan Blue Book". It's a regular Kaplan Prep book with just example problems from each section. The Big Blue Book you are after actually teaches you the material that will be covered on the OAT.
I do not think you can buy it new, unless you take the Kaplan course.
I have the book that is in your link, well the older version (2009-2010). And I bought it for only $10 on Amazon. ALSO I have the 2007-2008 version of the same book and it is THE EXACT SAME MATERIAL, SAME PRINTS, SAME EVERYTHING as the 2009-2010 version. So I sort of got scammed, and I would guess that this new version may be very similar to the old ones so you may be able to save some money if you get an older version.
I would take a pic of the big blue kaplan book for you but I let my friend borrow it. I think you can find a pic online somewhere...
And honestly, I think if you want to learn fast and effectively, go with CHAD VIDEOS, they are awesome. :]
Especially for the Physics section. I heard the Gen Chem section is good also. I only used it for Ochem and Physics though.
