It's a total pool of 100 questions and the list is available online. The examiner will pick 10 from the pool, and you have to get six of them right.
My wife had a CD that had the questions and answers, one after another. She listened to it (over and over again...smile) when she had spare time. You don't need a CD...you can sit there and read the questions and answers into an audio file (.wav, .mp3, etc.) and play it back on whatever you use to listen to music. There may even be online files that have someone already reading it all out and you just have to download one. "Over and over again" was the key for her.
I also got her the flash cards. But she didn't use them that much, and she tells me the CD audio is what got her to pass.
If you're someone who learns better by reading, print out the questions and answers and carry them with you. Take them out and read them when you have time. (You can also store the website or a document on your smartphone.)
Do not spend a lot of money on "aids" to learn with. It's not needed.
