I am in the same boat, however, hopefully, not for long.
Currently doing module 1 with BGS and working full time at MAN.
It's difficult to say how many hours I do per day because I do shift work. Some days it's zero, some 4. I always do at least 5 on my days off.
I don't mind saying that it is !!!!!e. It has been said many times before, and I couldn't agree more, if you don't have to work, don't do it. You can end up really resenting what can be an interestng course (arf!).
If I carried on like this I estimate it will take me roughly 12 months, plus or minus 1.
However, I plan on only working for module 1 and studying full time for module 2 which will seem like (hopefully) a relative walk in the park.
Whatever your circumstances, stick with it. And have some paracetamol ready for gyroscopes.
