To start with, I'm not sure whether this is the correct stackexchange site to ask this, but I can't find one for physics teachers and my problem could easily be extended to math teachers with the same problem.
I'm working for my university's physics department. They're looking for some software or tool that allows teachers to generate physics problems by plugging in values to predefined variables and generating different exercises based on that (as in, having an exercise archetype and generating different exercises by changing the values of these variables), then sending a different exercise to each student in the course, have them answer them, and then comparing those answers with the real values, taking into account errors (admitting a 1-2% error, for example)
Does such a tool exist? Thanks in advance.
