Thanks to the authors of HFSJ, Javaranch Team ,Enthuware Team and Frits.
After reading HFSJ, I was not confident enough to take the exam. I think its because - 1. lack of mock exams practise 2. failed in HFSJ mock exam, I scored around 60%only.
After reading previous javaranchers comments, I bought Enthuware mock exams and passed all the standard tests. I found Enthuware exams really helpful.
The level of Enthuware mock exams is almost same as actual exam.
HFSJ covers mosts of the theory but I needed more of the practice questions.
Finally, thanks to Frits for this wonderful notes.
