You cleared it with 52%? I thought a passing score was 43/72, or 59%?
Ooops. I see now that for 1.4 it was 52%, and for 5.0 it is 59%.
Being certified is like being pregnant, either you are or you are not. Don't fret your score. If you want to improve your skills, I'd suggest expanding your horizons. Maybe take up SCWCD, or perhaps you might get a much higher score taking the SCJA exam for the 1.5 version, then you could advertise on your resume being both SCJA and SJCP certified from Sun.
By the way, congratulations on the pass!
