Hi, Yes the above is correct.
Foundation year = 1 Year (duration)
and the rest of the course will = 3 Years
So total duration = 4 Years.
In regards to how to apply, are you applying via UCAS Or direct to the university? I am starting a foundation year course, and the course I applied for was separate than the normal course. So on UCAS there was a different option for 'Accounting and Finance With Foundation Year'.
