Why is Scottish BSc (Hons) 4 years while English BSc (Hons) is 3 years?
In Scotland, you can attend university after completing Highers, which are taken in the same year as AS levels are taken in England. Therefore, many Scottish students leave school a year earlier. Theoretically, the first year of university in Scotland is less advanced than the first year of university in England (although speaking from experience, I don't believe that this is practically the case). In recognition of this fact, it is often possible for English students to enter their course directly into second year, with a higher grade requirement.
