AP Comp Sci AB

<p>Hi! A few friends and I are independently studying comp sci AB this year under the guidance of our comp sci A teacher. So far, we've only covered Linked Lists, Stacks, and Queues. Are we moving too slowly? </p>

<p>Can anyone recommend any good websites with good practice problems? We're using the Barrons book as our sole source of information (no txtbooks or anything). Thanks!</p>

<p>No one's taking comp sci AB? I'll try my luck over at the Test Preparation board then.</p>
