I was wondering what the conditions are in order to be able to get a Phd?
What kind of grades do you need to obtain in your country to be able to do a Phd?

Or maybe other conditions?

In the UK you typically need a 1st or 2.1 degree or a 2.2 with a masters degree. A-levels aren't looked at, as far as I am aware. References are a BIG thing.
