The student/page/check code written at the top is

+\the\AMCid@etud/\thepage/\the\AMCid@check+

Thanks,

do you think it is possible to define a lua array and then use AMCid@etud to access
the elements of the array?

Let's say something like this

\directlua{a={1, 2, 3, 4, 5}}

\onecopy{50}{

\directlua{x=a[\the\AMCid@etud]}
%%% all the other stuff here

}

or similar. Basically I don't want to use random numbers to generate multiple tests but an array
of data defined in the TeX file using lua.

Thanks,

Never mind,
I found the solution in one of your previous posts and It works fine.
Using lualatex is a very powerful technique to combine with AMC.
