I have it. My dear, darling cousin gave it to me the day AFTER I passed my test. The idiot.
It really isn't THAT hard, I studied the K53 book only. It has two tests in the book to do, and that helps too. I did it over and over till I got 100%. Haha but even then I was still sick with anticipation but when I did the test it was quite easy. There are some trick questions but it's really hard to fail the test. Only one person writing the test failed the day I wrote...but that's because he couldn't read/write properly.
If you have Mxit, you can add K53 as a contact through Tradepost and you can also test yourself online at a website called salearnerz or something like that. The website has a rogue virus operating through their ads though, so update your antivirus before you go on that site!
If you don't have an antivirus download Avast AntiVirus, its free
