[Blind-sysadmins] simulations in certification exams

I'm new to this mailing list, and to mailing lists in general, so please let me know if I'm not following established rules. How do you handle certification exams that have simulation questions? The A+ and CCNA both had sim questions that I struggled through--especially the CCNA, because the combination of Pearson's testing environment and ZoomText made the screens hard to navigate. I've lost more vision recently and am not sure if I'll be able to complete these types of questions. Pearson VUE's accommodations team offered the use of a scribe/reader, but I don't see how that could work on anything but multiple choice questions.
