In Scotland, most* Degrees are 4-year courses.

*technically, the 4th is an 'honours' year, and you can graduate without honours after 3 years. This isn't that common for people who aren't struggling.

It's the same in India. Most Bachelor's degree are 3 years, but a degree in Engineering, which is also a Bachelor's (BS/BTech) is roughly 4 Years (8 Semesters) long.

Thank you for pointing this out. I wrote this late at night and forgot about regional differences in degree duration. I've corrected this.

Actually you can do this in the US too, but they are still called 4 year colleges here.
