You should talk to your family about failing uni, they will have to find out sooner or later, I myself failed 2 modules this year (first year if uni) and am pretty sure I passed the retake of one, but unsure if I have passed the other. I had to pay £100 in fees for the modules I failed. I have financial obligations on rent, that I have already started paying so if I don;t make the second year I will have to find someone to take my place in the house I am living pretty quick, I am already £600 in the red and the year has not even started!
If you knew you where gonna fail, did u make plans for accommodation next year, maybe you should have dropped out earlier or switched courses, most unis have advisors you can speak to on these kinds of things. Did you enjoy uni life, the going out ETC? I did A bit too much which is why I am in the **** :P
Your gonna have to pay the new tuition fees if you start a new course (Up to £9,000), as well as be in debt for the year you have undertaken with the student loans company.
You parents are likely to be angry if you have failed the first year, especially if your living with them right now, they may be less a angry if your truthful with them, but there your parents, I have no idea how they will react. Best thing to do is to talk to them.
Best of luck
