He's at Bristol. I would say the interview is THE most important aspect of your application other than entry requirements. After all its how you come across and your interpersonal skills which will make you a good dentist. Not your grades. Having said that, you will probably change and develop in sixth form. Most people do and you may well find that you become more confident and better at those sort of situations. But perhaps it might be worth trying to work on it with a teacher or something?
GCSE grades = fine, they're better than what i got.
Work experience, very important, get lots and plenty of variety if you can. Hospitals, GDP, ortho, dental labs. Whatever. Try to do block weeks and if you can, try and set up a longer term placement where you perhaps go once a week for a few months or something. If you can do it then it's great for showing commitment.
KCL are famed for GCSEs and UKCAT. I've never applied there so personally i wouldn't know. But that IS the steryotype if you will. But like all of the dental unis, you need to try and cover all the bases. Manual dexterity, Voluntary work, Work ex, a good personal statement and UKCAT. A good interview and a well balanced and varied set of interests. Some interviewers like to imagine you as their dentist, and ask themselves if they would feel comfortable.
I took about 2 weeks of solid prep for my interviews...as that was my notice period from the email till the interview. But you should try to read up on dental things and take an active interest when you're on work ex.
That is a great way to prepare. Bring a notepad with you and then you can revise from that when you go to your interviews.
Sporting and musical achievements are great. If you can work on those thats great. If you can't/don't want to. Then don't let it get to you, its not that big oif a deal, there are other more important aspects of the application process.
I hope i haven't jumped in on someone elses question, but i was going to reply anyway.
If you need any advice, send me a message or something yeah
