First off, congratulations Jonny! 73% is an awesome score.
I have a question along the same lines as the one you posed. For anyone who would like to chime in, does it really matter which version of the SCJP test we took? I know the most current cert is for 5.0; I'm certified on 1.4. Does this make me look somehow less desirable to a potential employer? At what point should I retest on a newer version? Sorry, just had a bunch of random neural firings.
