I just came back from the testing center with a 88 % passing score. And boy do I feel good now The K&B book is simply great, I studied with it and got this result. All I can say is "Thank you very, very much Kathy and Bert"
I am currently conducting a training course at work for those who would like to achieve SCJP (1.4) - of course, I am constantly queried for decent reference material; which book are you referring to ?
