Question bank with varying levels of difficulty

I am currently evaluating articulate on trial version to ensure it meets my requirement.

Normal 0 false false false oNotPromoteQF /> EN-US JA X-NONE

Requirement - > when a student is enrolled they are assigned default group and

when they start quiz, first they are given easy questions, when they appear to have runtime cumulative score of lets say 70% or more, articulate should automatically start the intermediate level of quiz for same topic, and then

further to tough questions.

Is it possible and if so, appreciate any pointers on it. Thanks
