Hi there,
I'm a graduate entry dentistry student at KCL. I got on through the 4 year course which allows you to skip 1st year and join straight into 2nd year. This is only possible if your undergrad degree is relevant enough. At A level I got BBDb, I got a high 2.1 in Chemistry with Biochemistry BSc and also did a 1 year MSc for which i got a distinction which I hadn't finished until I'd already started Dentistry so the grade wasn't taken into account. I got 667 UKCAT. I also had an offer form QMUL.
Some people say you have to have at least a 700 UKCAT to get into KCL but I know so many people who have got in either the undergrad or grad way with scores form 620 up. Also KCL are very interested in you being well rounded and NOT BORING. They are so bored of people with perfect grades. They get them all the time, but dentistry is not just book-smarts, so really try to convey the variety of of your experience and why they're helpful for dentistry.
7 of the 30 people who got on to the graduate course were already biomed students from KCL if that helps.
If you want to get into UCLan, you have to have done something in the life sciences- they didn't consider my degree relevant enough- so biomed, physiology, biochem degrees are the best.
Hope this helps!
