So I'm currently studying a level 3 college course in graphic design, on top of this I have another level 3 in Film and TV. I've recently firmly accepted an unconditional offer from my first choice university and I'm currently sorting out finance and accomodation etc. However, things at home are a massive problem at the moment as I may be facing homelessness along with other financial and family issues. I told this to my current course tutor and explained how I can no longer cope with continuing my college course and that I felt the best thing to do was to find a full time job to provide me with some sort of stability up until I leave for uni in September. I figured this wouldn't affect my place at uni as I have decent qualifications and already recieved an unconditional offer, surely meaning my course now isn't essential. After explaining all this to me tutor he proceeded to tell me that if I try to leave the course, he'll contact my university, tell them to not take me and withdraw his reference. Can he do this? Because I now feel completely stuck and somewhat blackmailed into staying on a course I don't need and can't emotionally/financially cope with right now.
