I am currently doing my ground studies at LMU.
The course will consume your life for the entire 6 months. You will be in class from 9 to 5 each day, and at the end of the day there will be more than enough to study at home.
Throw in the occasional progress tests and the intense studying required to pass some of them, and you will start to have an idea of how much time will be consumed from your average day.
I would not advise for anyone to try to hold a job or any other engagements during the length of the course because it will make life very difficult for you.
The main goal is to spend your time effectively and get the pass marks during the course, then you have the rest of your life to pay off your debts working from the world's most fabulous office!
