OASHI: jeste k diskusi na verejnych forech od Adv. level ISTQB, chlapik Ind se tam ptal, jak se ma pripravit na AL, kdyz jsou tezko dostupne materialy, hlavni guru mu odpovedel:
There are a number of pointers to books in chapter 11.2 of the ISTQB AL syllabus version 2007. You can also look at the different standards mentioned in section 11.1.
That, plus the references present in the Foundation level syllabus should be a first step to self training.
However you should be aware that the AL certification is very difficult and open only to experienced testers with a number of years testing experience.
