It's good, you kinda go to GU more for the reputation than anything. It's a lot of continual assessment so I would say places like Strathclyde are equally as good and from what I can tell have a much higher student satisfaction than GU does
The programme is alright. As an international student the fee is around £20 000, which is quite a lot. According to the ratings it's supposed to be a good uni, but the main difference is probably not the skill level you get, but rather the employability .
