Sun feels that you are competent in SCJP if you score above the minimum marks.
Programming in any language does not so much depend upon your understanding of the language syntax as upon your logical and analytical brains.
So Sun says OK if you pass atleast with this minimum % you are ready to program with
java.
So what does the % indicate? That you are an excellent programmer if you get 100% and not so excellent programmer if you get 52%? No sir,it simply indicates how you answered in the exam.
So would you hire a person as a programmer because his SCJP score is higher than the other?
What happens if we start programming in another language?And what if the person scored 100% two years back( remember SCJP score is valid only for two years!)?
SCJP score,over the minimum, is only for self satisfaction.You can jump with joy that you met minimum requirements or sulk because you could not get 100% when you actually scored 95%.
The choice is yours.( and your employer if he/she happened to have scored 100% in scjp
