Spils,
How long is a piece of string? You can, if you have enough spare time, work on the studying full time, in which case there's no reason why you shouldn't be able to do it in the same amount of time as a full-time course. Or you can take a couple of years over it. Most people go for somewhere in the middle - it took me 12 months, working most weekends and occassionally after work.
