Thanks! I didn't think so, since the official training kit doesn't cover it at all, to my recollection. And in my past experience, practice exams tend to be harder than the actual exam (if you find the right ones) so here's hoping! I do plan on focusing on XML a lot this week as that is my weakest area, but since they do list it under their exam specs I'll at least have a brief overview of the 4 different spacial aggregate functions and what they do. Thanks again!
