Check if your uni has any bursaries available that you can apply for and don't tell your parents if you get one.
Also double check if you can get a job, im not 100 % sure, but you i think as long as you can prove you have a certain number of uni hours a week then you might be able to get a job, unis will usally have ones where it's such as uni ambassador or TA once you in second Yr. But again I'm not 100% sure.
You should have enough money left over from loan if your parents aren't overcharging you. If you get a seasonal pass you might be able to save on transportation costs. But calculate everything and see how much loan you're entitled to so you have a better idea of how much money you gonna spend in uni.
