I have graduated from Oxford, having done a BA in Biological Sciences. Although the course was difficult, and the testing was rigourous, it was a thoroughly fantastic experience. The university staff were incredibly supportive, and I got the chance to work with so many of the world's leading experts in particular fields of my subject. I would recommend anyone to look at the various access schemes available, if they come from a school or family that isn't familiar with the Oxford admissions process.
