Don't panic!
I'm in the same situation as you, and did UKCAT this morning. I found the demo questions on the website in the QR section impossibly difficult: the ones in the actual test were much simpler. (I wish someone had told me this last night: I was properly bricking it...)
As a graduate, you're additionally much more prepared for the VR section (having presumably read much more complex academic literature than what is used in the actual test) IMO. Don't worry if you're getting low scores in the example tests for this section in any books you might have bought: they appear to be written by idiots. The one on the UKCAT website is much better.
You get given a laminated sheet of paper, a marker pen and a basic office calculator to use.
Just relax: 17 year olds can do it
