Clearing at Kent is still open until the 18th October and there are still places on the Psychology course!
In order to get the quickest response, I'd definitely recommend giving the clearing hotline a call ASAP on +44 (0)1227 768896 (I'm pretty sure it's open 9-5?) and they can talk you through your options!
I'm probably a bit biased, but I personally transferred to Kent in the second year of my undergrad and have since gone on to do my master's and PhD here in Psychology & I absolutely love it, so would definitely recommend!! The course is also accredited by the British Psychological Society & Kent ranked 16th for Psychology in the UK for graduate prospects in The Complete University Guide 2023.
Best of luck with everything!!
