Hi Shatabdi,
I had given one techchek Java 2.0 programmer test and found that it is very similar to the SCJP(in terms of the difficulty of questions asked, topics covered etc).
But the way it is evaluated is different.
It has negative marks for wrong answer and in addition the wrong answer given is also weighed. For ex. If the question is : In Java Threads are scheduled by implementing
a. Preemptive scheduling
b. Time-sliced or round-robin scheduling
c. They are system dependent
d. There is no Threads concept in java
Here the correct answer is 'c' but if you choose 'a' or 'b' then you loose less marks than if you choose 'd'.
Also the questions are adaptive i.e. If you answer correctly then the next question is slightly tougher, but if you answer it wrong then the next question would be easier.
Additionally, your score is compared with all the others who have given this test (with a statement like you scored higher than 65% of all other candidates who have taken this test). Note: You will not know the result, only the employers get to see your scorecard.
Hence it is possible to pass with fewer correct answer (which are considered to be tough by Techchek) and also fail if you have answered many of easier questions.
Hope this helps and all the best
