Tired of studying alone? Wish you could match your wits against a friend's or friends'? With PrepZilla, we've turned exam prep into a game. It's not just fun. It's serious fun!

Browse our growing library of test prep titles from top educational publishers including McGraw-Hill, Florida Virtual School (FLVS), CCI, and Barron's and select one (or more) that best meets your exam needs. Each topic comes with a set of free questions and is expandable to many more. Are you preparing for the AP Chemistry exam? Then McGraw-Hill's 5 Steps to a 5 AP Chemistry app is right up your alley. With two study modes, you can review the topic on your own (Self-Study) or with friends using the group play option (Who Knows?). Or maybe you're a nurse preparing to take the NCLEX-RN exam. Review the material on your own or invite a couple of friends to study along with you, challenging them to answer questions you select whenever they have the time. It's that simple!

In Self-Study mode, review the test material on your own by taking a timed quiz or browse through the questions and answers at your own pace. It's up to you. Want to have a little more fun? Select the new Zombies game and rack up the points as you review the material and have fun in the process. This dynamic app also allows you to flag questions as you go, thus allowing for easier review of problem areas. You can even create a quiz composed solely of these flagged questions. Detailed analytics allows you to review your quiz history and statistics like your weekly progress. You will also discover your category strength and weaknesses.

When you're ready to challenge a friend, send them an invitation by entering their e-mail address into the app itself or use your Facebook friend list and wait to see if they're game. PrepZilla allows you to take turns selecting the questions you both will answer and tracks the points you need to win. Feeling lucky or just well-prepared? Users can double-down on their points to pull out a come-from-behind victory. Your opponents will never know what hit them.

Don't see a current title that appeals to you? More topics will be added to the PrepZilla library soon so check back often.

PrepZilla may not have you scaling the Empire State Building any time soon but it will help prepare you for the next exam on your horizon. And, who knows, you may get so wrapped up in playing the game, you'll forget that you're even studying. Sweet!
