Hi All, I cleared SCJP 1.5 with 80%. The K&B preparation book was of a great help. Also, I would like to thank the javaranch community as the questions put up by different members were of a great help in clearing my concepts.
A note on the strategy I followed for preparation. I solved a lot of mock tests and after each mock test tried to classfy my incorrect answers into two categories. 1) Errors due wrong application or "silly mistakes" 2) Errors to inadequate understanding of concepts Then I worked systematically to improve in both these areas by solving more questions and re-reading those chapters from K&B book respectively.
This approach helped me in improving my scores considerably in a short time. I also practised from the whizlabs and Javabeat prepration kit. I feel that the mock tests in K&B book and Whizlabs are much tougher as compared to the actual exam I as could only manage about 60-62% in these test!! Thanks and all the best to everyone.
