Scottish Bachelors take 4 years, in England they generally take 3. In Scotland, the first year is for trying out different subjects and disciplines. For example, I applied to study Sociology, but in your first year you have to take additional courses, so I chose English Literature, Anthropology, and French. Turns out, I really love Anthropology so I changed my degree to joint honours Sociology and Anthropology. In England, you don't have that flexibility.
So if you are 100% sure what you want to study and you only want to do three years, choose Coventry. If you maybe want to try different courses as well and you don't mind the extra year, go to Aberdeen.
I can also really recommend you to take a look at the "@studyinaberdeen" Instagram account. It's run by a student and they talk about all sorts of things, such as academics, student life, etc. They also have a "A day in a life of an Aberdeen Uni student" and are super helpful. So check them out. Maybe Coventry has something similar
