Ooooh! That sort of thing really annoys me.
I got onto my course at a former poly on the strength of a couple of OU passes. I was also made an unconditional offer for an alternative course based on work experience alone.
At the time I applied, I also applied to our local 'red brick' uni. They called me in for an informal interview where they said, in so many words, "We don't think you'd be able to hack it, but we wanted to see you just to make sure. Of course, if you did one of *our* access courses, you'd be guaranteed a place.". They also later turned me down for a PGCE course on the basis that although I had the requisite GCSEs, I didn't have an A level in my subject (the OU courses didn't count, it seemed). Ergo, former access students wouldn't have a dinky's because if they had A levels, they wouldn't have needed the access course in the first place.
In the event, I did my history degree and got onto my PGCE course at the former poly, and I don't regret it for a moment. It was three of the best years of my life, spent with some of the most fantastic, down-to-earth and non-snotty people imaginable.
If I'm ever famous and the red brick uni offers me an honorary, I'm going to turn it down, but I'm going to wait until the ceremony to do it - very publicly!
