It's 3 years undergrad, 1 year working then 1 year masters.
I have lectures Monday-Thursday with only a few hours in the evening to eat, do housework plus study. I have to work Sunday so that only leaves Friday and Saturday to do uni work plus have some time to relax. That's a more demanding schedule than when I was working full-time.
The reason for wanting to go back to uni was that my job doesn't really have any scope to progress beyond where I'm at now so I feel a bit trapped.
I kind of feel like I'm giving up all my spare time,money,hobbies,holidays etc etc to go to university and it's seriously daunting to think of this happening for another 4-5 years!
