Just heard a rumor (I don’t know how true it is) that if you fail one unit, you may have to repeat the whole year. My mind is racing. Is this true, or is it another campus myth? I feel some tension considering how much I’ve been struggling in some units this year. What's the real deal with resitting exams or supplementary papers? How does it work?
