Hey Vladas,
I plan on reading the spec upon completion of Head Start. I have been reading bits and pieces while working through Head Start. Recently I read a posting by Kathy Sierra stating what parts of the spec are not covered by the exam and could be skipped. I just don't recall where I found the posting. If someone knows where to find it please post the link.
Good luck on the exam. I hope to be ready to take it before the end of the year.
