HP Prime and ICGSE/A-Level exams

[mcjtom]

Would anybody know under what specific condition the HP Prime was allowed for use on the AP exams? Did they specify what needs to be disabled in Exam mode?

Even though I've corresponded with the CIE for a month on it, it's still unclear to me what would be OK for IGCSE/A-Level exam: providing clear answers do not seem to be one of CIE's fortes. Their guidelines seem to ban any 'graphic display', yet in other documents there is only mention of 'calculators capable of plotting'. Main justification for the ban, as I was given, was to force students to learn how to eyeball best fit regression lines through a scatter plots.

Under such rules, there are obvious Apps that need to be turned off, such as CAS, Function, Advanced Graphing, and Stats graphing (I guess that means all the stats as I don't think graphing can be separated from the numerical part of the App.), but there are many options that are less then obvious. So for instance, Triangle Solver - it doesn't plot anything, nor it is a 'graphic display' application, yet it shows a triangle, which is 'graphic' I suppose.

It's easy to turn off everything, just in case, and unnecessarily lobotomize the Prime even if the specific exam regulations don't really call for it (it happens to be CIE in my case that has the graphing phobia). So here is the challenge: what is the minimum set of functions and Apps in Exam mode that needs to be disabled to satisfy the exam rules, leaving the greatest possible range of functionality untouched?

Cheers!

p.s. I can't find it, but perhaps there is a way of disabling Plot button in all Apps - that would likely satisfy most of the CIE restrictions, yet wouldn't kill numerical capabilities of Apps like Solve or Stats....

CIE also restricts 'data banks'. Would that mean that Inferential Stats distributions would have to be turned off? How about constants?
