Hi!
I have dropped out of university twice so I am well versed in this topic lol. Firstly you must contact your course director and explain the situation. they will probably have you fill out a form for your reasonings. Depending on the time of year you leave will depend on how much of the tuition fees you owe. If you have not left yet it is likely you owe 100% of the fees for this year. So in total your student finance should be year 1 & 2. You should not have to pay for year 3. Also you are not expected to pay this upfront it is just on your student tuition bill which you will pay back if you earn above the threshold. ( i am unsure what this is you would need to research) In terms of student loan this should be the same, you only pay back if you earn enough money in your job.
