I would develop two versions of your online learning project within the same project. Make sure you select branch aware from the Preferences / Quiz / Settings so that skipped questions are not marked as incorrect. Early in your course ask the participant if they wish to have their training in English or Azerbaijani. If they select English you jump to slide 2 (for example), if they select Azerbaijani you jump to slide 50. At the end of each path have them jump to a common final slide that shows them their results. The key is making it branch-aware so they are only scored on questions they see and not the questions from the other branch.
