I cleared the SCJP 5 with 91%. This forum has been extremely helpful in understanding the finer concepts of JAVA. I used K&B as the bible. I had to go through the book at least 3 or 4 times to get my confidence up. Reviewing some of the posting in the SCJP forum helped me. I had time to take only one mock exam that came with the K&B. I believe reading the K&B with full understanding of each and every concept is the key for clearing the exams. Also I had to do hundreds of small programs to understand some concepts which were not explicitly mentioned in K&B.
