Hi, I'm a 2D animation 2nd year at the university of Hertfordshire. Our course ranked as the best in the UK on last year's rookies (best games art course in the world even) We have 4 pathways: 2D animation, 3D animation, Games Art and VFX.
In first year we have most classes together regardless of what pathway you're on (and you can switch pathways too if you want, a lot of people do), and then we get to specialise further in second and third year (which people from the industry seem to appreciate about our course, considering most people from other courses seem to come out of uni as generalists and then specialise while in industry, while our alumni get to already work as what they specialised in (say modeler or animator (this is mostly 3D people, as 2D generally end up working in 2D studios or as storyboard artists and similar, while 3D animation, VFX and games have more of an overlap in industry)))
We don't focus as much on stop motion, considering we're a digital animation course, but we did have a small stop motion project in first year as part of our artskills portfolio.
I am not really the best person to tell you about 3D animation (as I'm 2D myself), but I could send some of the 3Ds over here if you want.
