I
passed the ZCE exam on 24th dec, 2011. I would like to share my exam
experience with you.
I
went for exam at NIIT Ltd , Cannought Place, New Delhi. I already
scheduled my exam via Pearson Vue.
At
Exam Center, When I Informed that I have already scheduled my exam at
11AM, they were surprised!!! It seemed that usually people directly
go to exam center without even scheduling.
For
exam, I wasn't allowed to keep any blank paper or pen. They gave a
writing board and a marking pen.
There
were total 70 questions and time allotted was 90 minutes. Questions
were of single choice, multiple-choice and open text questions. For
multiple-choice questions , it was clearly mentioned on how many to
choose. On choosing more answers it gave an alert. However, if you
choose less, loss is all yours.
During
the exam, Computer got switched off twice. As expected on restarting
time counting started from where it was left.
I
was done with the paper in about 50 minutes. Rest of the time I
reviewed my answers. As per my review, out of 70 questions 48 were
for sure correctly answered. Answer for 1 question was a blind guess.
And for the rest of the question, I gave logical answers. In all I
guess about 60 questions got correct. I was lucky enough to get the
exam passed.
I
have 2 years of experience of developing with PHP, and I believe that
practical exposure is must in order to clear the exam. Exam wasn't
about the theory part at all.
You
must be clear about below types of questions before going to attemp
