Does it matter? I don't think we need the book samples. Anyway monson haefel dot com used to have some link for it earlier I think. In my opinion, best thing is to code using hand and play with them if you need to pass the exam
I am really so to hear your case. I too purchased whizlabs kit for the same purpose. I hope the same doesn't happen to me next month. In your place I would practise harder and crack it. Good Luck
