Swansea is pretty good for aerospace. In terms of league tables they are above some Russell group unis such as Manchester and Birmingham. I had some flatmates doing the course and they said it was intense and hard work, but the teaching quality was generally very good, which is the same for my subject which is non-engineering. Just make sure you stay on top of your coursework and you’ll be fine.
Bay Campus where engineering is taught is also brand new so you’d be taught in brand new lecture theatres and labs.
