Help! Uni student in need!!!

Ok so I have been retaking my first year of my uni degree which is Sports Therapy and Rehabilitation after failing my exams last year, I failed the same ones and realized that I don't want to do this anymore and I want to work in the job I have now (retail) to find out what I want to do for the rest of my life. I signed a new contract when I moved in to the place I live in now which is a private rent student house as it was cheap rent all bills included... Now I will need to move out but have been told that I aswell as my housemates are responsible for finding a new person to live in the room I am in now... and if I don't will probably have to pay half rent on top of the rent I hopefully the new house I will be moving into leaving me with next to no money after I have payed the bills. As I have signed the contract to say I was going to live there until June 2024, can I ask my landlord if I can stay where I am living now and still pay rent just have to pay council tax on top???
