Anon is just making a fake post. Literally no college would authorize this type of shit and I'd argue there could be grounds for a civil lawsuit if they did. Paying them tens of thousands of dollars and one of their professors admits to just auto failing students because there's too many in the class? Nah, I've attended 3 different schools before I graduated (I moved a lot), and every single one would drop you before class even began or within the first week if the class was too full.

If this did actually happen to OP, I can guarantee there's more to the story they're not telling us. But I'm going to assume it's made up or extremely exaggerated/altered.
