I cleared my SCJP 1.5 with a score of 81%. I have to thank Javaranch for helping me with the preparation. I read through K&B book, revised and did the mock exam in the CD that comes with the book in Open book mode and also coded a lot. I couldn't do other mocks, was running short of time and my voucher was going to expire. Maybe I should have given more mocks. However, I am happy with the score, and happy to have finally given SCJP which I have been planning to since a while.
Many of my doubts have been cleared from the SCJP forum, the replies have been prompt.
