The digital campus tutor is available at any hour and knows the context: the open lesson, the current exercise, the skills already validated and those that still need time.
Its conduct is set: it makes the student produce. Faced with a graded exercise, it questions, breaks the problem down, offers a neighbouring example and points to the part of the course that holds the key. Students write their own answer, and that answer is what gets assessed.
This choice protects the value of the award. Submitted work must remain the student's own, otherwise assessment stops measuring anything and the certificate loses precisely what gives it value with an employer.
Exchanges feed the teaching follow-up: when the same notion comes back repeatedly, the cohort supervisor is informed and the teacher can take the point up again in a live class.
