Unfortunately I don't have a very good answer for this. I'd suggest you start by looking at the istqb website for recommended training material, talking with local trainers, and amazon seems to have a wide selection of books as well.
Anyone taken the ISTQB Advanced Technical Test Analyst certification exam in the UK? Where can I get exam practice material? I know iSTQB website has got a few sample exam questions on their website, but there are just a very few of them, and it looks like they are intended to only guide exam writers in coming up with exam questions. Any pointers would be appreciated.
