If you’re having trouble accessing those free Kaplan test prep books we told you about a few days ago, make sure to download the iBooks app first. It makes the book download happen all lickity split.

Earlier today I was trying to get the books on my iPhone 4 and the screen just kept flashing between a Safari page and an iTunes page. After getting the free Apple iBooks app, though, the books downloaded quite smoothly. Now I’ll be sweating over logic problems in no time.

To recap, Kaplan is giving away over 90 free standardized test prep books, but you’ll have to visit http://kaplanpublishing.com/iTunes on your mobile browser to get access. SAT, MCAT, GRE, ETC. ETC, it’s all there free until August 30.
