Anyone attending any lecture must… have his own copy of the reading or a borrowed copy for the time of the lecture (two or three students at most may share the same copy) and, without a reasonable cause, except in the case of a legitimate impediment, he must miss no lecture that he was supposed to hear, or exercise which he was supposed to attend, from the third lecture or exercise after the beginning of the book, and as much as he is able, he must remain from the beginning to the end of the lecture or exercise, nor may he schedule two lectures or exercises at the same hour. However many times he has missed an exercise or lecture, or has not remained from the beginning to the end, and all his other failings, he must note down in the outline of his acts, to be presented at the time of the dispensation, along with the excuse (if he has any), and he must write and explain and seek a dispensation, so that according to the greater or smaller number of his negligences and failings, and excuses (if he has any), the professors will be able to deliberate and decide whether he deserves a dispensation.

Whatever the excuse (if he has any), I guarantee those profs have heard it before.
