Hi Himani and Marc
I just cleared my SCJP exam
my perception is that the real exam is a little more easier than the enthuware test series.
Like Himani you scoring 60to 70% at the moment just add 10% more and that will be the score you will have in your exam.
But I think when you start feeling confident enough and you feel that you will be able to clear the exam just go ahead and give it
Wish you all the very best for your exams
