<p>i'd love to be able to study on the bus or in the car without having that big book in my hands.</p>
<p>I’ve got a flashcard application on my iPhone called Mental Case. You can either make your own flascards or download flashcards from Flashcard Exchange (which has a lot of vocab derived from prep books). </p>
<p>There’s also an app called Study Sets Psychology which is pretty useful for anyone taking the AP Psych exam. </p>
<p>Just do a search on the app store if you want an app for a particular subject and you’re bound to find something.</p>
<p>There’s also Cram, which is on the iPhone and I believe iPod Touch as well and Mac.</p>
<p>Maybe that will help</p>
