22 year old girl. I am a student Looking for student accommodation

I am a 22 Year old student coming to Oslo to learn Norwegian language before getting admitted to the university. Before coming to Oslo, I lived in London for about 3 years and studied in UCL in the Pharmacy major but I want to pursue my studies in Norway and that is why I am coming to learn the languag.

I am preferably looking to live in student dorms as I feel much more comfortable but if you can provide me some suggestions regarding the rooms available in central oslo which is close to my college would be absolutely  perfect. I would be very much appreciative and looking forward to hearing back from you.
