There's a very revealing comment on the Educational Conscription blog:
Having been the admissions tutor for my university department for many years, I can assure you that is not the case. In my subject (Computer Science) we were quite clear that a lower UCAS point score including useful subjects, like Matehmatics would get you a place, whereas a higher UCSAS score including useless subjects like "Information Technology" would not.Information Technology is, in principle, closely related to Computer Science. In practice, it isn't. It is a dumbed-down easy option that has little value.
Are schoolchildren made aware of this when they have to choose their subjects?
