Finally cleared SCJP 5.0 with 77%, feeling relaxed now. The book from Kathy Sierra and Bert Bates is an excellent and enough study material for the exam. No need to study from different books and tutorials from the Internet for the exam.
The paper is not very tough and can be cleared with K&B book, the book is exactly matches the pattern and cover the topics of exam. The mock exam questions given in book and CD comes with book are enough for exam, and are more difficult than the actual questions come in exam.
If you study too much for the exam and try to solve many mock exams available on the net, than chances are that you got puzzled like me.
