Sun considers changing SCJP to "adaptive" format

I'm considering taking the SCJP exam within the next week or two, and now I read that Sun is considering modifing the exam somewhat. Does anyone think that it would be worth waiting to see if Sun decides to move to this "adaptive" format for the exam instead of taking it this month? Thanks...

How long have you prepare for the exam? It's obvious that computer adaptive test requires a different strategy to approach the problems.
Just a few points for thought.
One obvious difference is that you will get deduction in marks if you answer wrong. You've to spend extra efforts in the first few questions in order to pump your marks to a sufficiently high levels.
But its advantageous in the sense that you can finish it in, perhaps, just 20 or 30 minutes, assuming that you get the answers right all the way from the beginning. This is good for people who have problems like loss of concentration or fatigue etc., if staying extended hours in the exam room.

To make things simple, the keyword of adaptive test is 'adaptive'. That means, the difficulty level of the questions are 'adaptive' to your ability to crack them.
Generally speaking, you're assigned easier questions in the beginning and an initial mark of, say, 61%. If the computer 'senses' that you can answer these questions without any problems, your marks will be continuously increase. Say for the 1st question, from 61% to 67%, 2nd correct question from 67% to 71%.... The computer will then progressly assign you with more and more difficult questions. However, if you miss one question, your mark will be dropped and the computer will then assign you an easier question. The test will stop when the computer can 'confidently assessed' your skill level. One example is you always miss those questions at a particularly difficulty level.
Of course, the implementation is very flexible. This is just the general idea.

The Novell CNE test was this way. On some of the tests you could get out after answering as few as 10 to 12 questions (if you got them all right).

If they do go to adaptive it will take at least 6 months to set it up correctly, so go ahead and take the present test. You have to gather a huge bunch of statistics with your question set to make a good adaptive test.
