Is college easy for people?

Few genuine questions....im in third year and something or the other keeps baffling me about people or cllg
1. Is college easy for people? Or is mine just too too hard? Classes till evening, barely time for lunch, assignments with insane deadlines, group work from hell...
2. How are people so absolutely, completely, BRAIN DEAD...? You talk to them, and they don't understand it, they don't know basic stuff even in their third year and they can't do anything by themselves without spoonfeeding....

Idk maybe I'm rambling from exhaustion of so much terrible group work but I seriously wanted to vent how fucking terrible college makes me
