I'd like to know if there is solution for tasks individualization. For example, task is to find 3-numbered key in file but I want different key for every student to be an answer. I wouldn't mind if they should use some kind of their personalized number to be recognized first. Is there any plugin that is at least similar with this description?
My next question is if there is any plugin that can help me with limiting how many students can choose one topic for seminar or presentation?
