Re: [NTG-context] Randomize order of blocks

7 Jan 2021

      Nice. I had something a little bit different in mind, but your examples
gave me some ideas, especially the shuffling stuff. If I have something new
to add, I will share my results with the list. Thank you a lot.

Best regards,

Jairo

Following up my previous message, here is an example:

                tt = {}
                t = {}
                for i = 1, maxsize do
                        t[i] = {}
                        t[i]["columnOne"] = tableau[i]
                        t[i]["columnTwo"] = math.random(1,100*maxsize)
                end
                table.sort(t, function(a,b) return a.columnTwo <
b.columnTwo end)
                for i = 1, maxsize do

Hi Jairo,
One can indeed make quizzes and exams with randomized order of problems,
randomized values and even randomized names of functions and variables.
I have some examples which I have been using for several years (they are
useful especially in these days of giving exams online…): I can send them
to you as they are, or if you tell me what kind of problems you want, then
I can adapt my examples before sending them to you.
Best regards: Otared

Hi, list.
Some time ago I realized ConTeXt has "blocks" which allow one to make
quizzes, exams and related with ease. However, I want to know if there's an
option to randomize their order when printed. Thank you in advance.
Jairo
