I passed SCJP 1.4 with 88% on 8th May, 2005. I have core java programming experience for more than 4 years.I wanted to write SCJP for long time but couldn't spend much time on it. Finally I have practiced all the mock exams listed on this (javaranch) site for one week and passed with 88% sore.
I really thank you all great people.
