"AP" review books for college students

As a student who studied over the summer and thus received A’s in copious AP classes, I want to alleviate as much stress as possible throughout my next four years. As an incoming engineer, I want to prepare for the rigorous classes I will be taking. What books do you use–if at all-- to efficiently prepare for college courses? I would like to purchase compendious books that rival the comprehensive yet concise nature of AP review books such as the Princeton Review and Barron’s.

What brand besides Dummies are out there?

Postscript: I am currently using textbooks; however I think this method is too slow.
