I need a plug-in or other help to create branching-logic exams. In other words, exams where if the student chooses one option, s/he goes down one path, and if s/he chooses another option, s/he goes down a different path. Any advice?
Have a look at the documentation here - you can set a score on the lesson module and so it might be suitable for an exam, and you can set branches according to their choices: http://docs.moodle.org/en/Lesson
