Mac OS X Tips has teamed up with SimpleLeap Software to give away 3 free copies of Cram, their software for studying with flash cards and multiple choice tests. See the bottom of this post for details on how to enter the competition.

Cram is an application for creating and sharing flash cards and multiple choice tests to help you study. The interface is all very intuitive, and it comes with a few pre-made tests which are great for getting you started and showing you how everything works.

The two main ways to use Cram are to either create your own tests or to browse the tests in the online test portal.

Creating your own test is pretty straightforward. For each question you write, you can enter up to five possible possible answers to choose from. You can either manually choose these for each question, or you can create an "Answer Bank" that contains all the answers for every question in the test (and also some incorrect answers if you want) and then randomly assigns them as the multiple choice answers to each question.

Drag and drop adding of images and audio to your questions is also really simple, and you have the option of setting a time limit to your test.

Once you've created your test, clicking "Study" in the toolbar will allow you to view your questions as flash cards that you can flip over to see the answer. Then as soon as you are confident enough, you can start the test. Cram also keeps a detailed test history so you can track your progress and see if you are improving.

The Test Portal is the alternative to creating your own tests, and it's probably my favourite feature. It contains over 2000 tests on all sorts of subjects submitted by other users. Unfortunately most of them don't seem to be organised into the right categories, but the search feature works well enough to overcome this. Each test has a name and description, and once you've found what you want simply clicking download test will add it to your collection. Of course you can share your own created tests just as easily by selecting them and clicking "Share Test" in the toolbar.

Overall Cram looks like a great resource for students or anyone studying for a test where they have to memorise things. It seems particularly well suited to particular tasks like learning foreign language vocabulary or dates in history.

You can download a demo for free, and purchase the full version for $34.99.

If you want to win a free copy of Cram, just answer the following question. The winners will be chosen at random from all the correct answers.
