I had to do a Java 6 IKM test the other day. I thought i’d post the result sheet up because it looks whizzy.
You’ll notice that there are two scores – a percentage and a percentile. I think that the percentile is the important one, as 2 people can get the same percentage accuracy while one answers much harder questions due to the adaptive nature of the test (plus time might play some part in the percentile score too).
It’s hard. Way harder than the SCJP or whatever Oracle call it these days. I had the advantage of being able to bone-up over the weekend as I was expecting this test to come my way.
It’s an adaptive test which means that the difficulty adjusts on-the-fly depending on how well you are performing. This makes it a better test, but BEWARE… because of this you cannot skip a question and return to it later.
There can be up to four (if I remember correctly) correct answers out of 5-ish options, and the points you get for your answer will depend on how close your chosen answer/s are to the correct answer. This means that, for example, you may score partial credit for selecting a reasonable, even though incorrect answer. In the same way you will score negatively for selecting an entirely nonsense answer. I like this mechanism as it accounts for random guesses, while rewarding partial understanding with partial credit.
There was a time limit of about 2 hours.
