Julian -
a) How many SCJDs there are? I'd be particularly interested to know how many there are in the UK. And even how many as a percentage of the total number of Java professionals. Has Sun done any research on this?
Stats aren't published for the certifications. I sent a question into Sun regarding this a while back - ]
here is a URL related to their response.
b) Has anyone got the perfect 400 score?
At least one person has - see
George's results
c) When did the maximum score change from 155 to 400?
I don't know the exact date, but my guess is sometime in spring 2003. The
SCJD FAQ page gives some information about the different assignments, but doesn't specifically list when the new assignment came out.
