Going to UCL this autumn but there's something about uni courses that has always confused me. Let's say you want to do comp sci, the entry requirements at imperial are A*A*A but at somewhere else it could be BBC. Both universities need to teach roughly the same stuff right but how can students with poorer A-levels successfully complete the degree to a high standard and how can employers trust that a degree from x is the same as y? I understand some students get much better at uni so perform better post A-levels but still.
