This morning, I have passed the exam with 89% ( 62 /69 ). Thanks so much for this great forum!
HFS book helped me a lot for understanding. Also, I have purchased the JWeb+ mock exams. All mock exams are very helpful, I used to get around 75% in JWeb+ mock exams. There are some typos and incorrect answers, but overall good collection of mock questions.
2 days back, I wrote the HFS mock exam and got 58% only. I felt very uncomfortable, took a deep breath and refreshed all again, for 2 days (30+ hours).
