I have passed the SCWCD 1.5 certification exam with 81% score.
I have read the book HFSJ twice, but the most important factor that helped me with exam was the mock exam.
You gotta believe me that i have seen the same questions in real exam that i had gone through them in mock exam.
There is one mock exam from wroxexam almost 250 questions, helped me a lot.\
You gotta give enough time for mock exams to score better.
Anyways, thanks for everyone help for my queries ;-).
