Hey
I know theres one in Prague - Charles University and their tuition fees are around £11000 and english taught and it is recognised by the GDC so you can practice here.
However I got told that the actual course itself is very hard, like much harder than UK ones. And also, you would need talk to your patients in Czech, so there would be a communication problem although the uni apparently provides a course to learn the language but personally I think it'd probably still be hard to communicate with the patients, especially the stubborn ones.
Grades wise, I'm not too sure, but I know you had to do ann entrance exam before but they emailed me saying that they would look at A-Level results itself from now on, so I got a bit confused on that and everytime I tried emailing the lady, my email wouldn't sent -_- so I kinda gave up.
But yeah basically theyre more interested in the money. Another uni for dentistry is the one in Slovakia, and its slightly cheaper but same problems with communication I think.
Hope that helps.
