I got a conditional offer for a degree I didn't apply to, and I'm confused about what's going on... does this happen usually, or is it a mistake?
What did you apply to and what did you get an offer for? what are the entry requirements for each and what are your predicted grades?
Sometimes if they like you but there isn't room on the course you applied to, they'll offer the people at the lower end of the requirements/ that are better suited to a different course, a place on a similar course.
For example my friend applied to a course which asked for 240-300 points. She was predicted 240. They offered her a place on a very similar course who's requirements were 220-260 I think. this was applying for 2011 start, so there was a mad rush of people applying to avoid the 2012 fee rise, thus even though she met the minimum requirements, there were lots of people applying who were predicted grades at the higher end of the range.
