Exactly, you create a token for each course-teacher-participant combination. This means that one participant could have various tokens if he participates in various courses.
If you create your tokens yourself you can even create them including this, eg. first two digits for the course, 3-4 for the teacher and 5-6 for the student. However, this is dangerous because some students might figure out the pattern and use it against you...
In the questionnaire itself you can make use of the attributes in the token table. You can directly reference to them from the survey (e.g. great the student by his name, filter questions based on the course, pipe in the name of the teacher).
If I am right you can even export the token attributes with the results if the survey is not anonymous.
