What Can Be Made Up and What Cannot

Our life is such that many of our actions entail irreversible consequences. A seminar missed with one’s own group cannot be made up. No joke: every seminar is unique (some better, some worse, but they all go differently), and, like any unique moment in our life, it cannot be repeated. A test missed with one’s own group can be written with the next group; after the tests have been written, they also are not repeated. However, you did not write about seminars or tests, but about ecology in general. Here everything is simple: come to the credit assessment, draw a ticket, answer 4 questions from 4 modules, and receive a grade. It is entirely possible to earn an A (although it is easier to earn the same A during the semester). Good luck!
