It would be nice to have into the course core information (the page with the name of the course, the short name and so forth) the "estimated required studing hours" of foreseen home study or of the foreseen connection time. This would allow admins to add to the certificate the info like: "This certificate states that mr. x, attended the course y requiring 60 hours of personal study". 60 is the new string I am asking. This number give a weight to the certificate. It distinguish a simple/silly/useless paper from a heavy/strong/valid/important certificate.
Thank you in advance, if it is possible.
