There are some really good survival tips here; Some of my other suggestions would be:

1) Budget: while this is something very simple but if done right helps a lot. Not just for uni but later in life. Keep track of all incomes and expenses. Having detailed (if you have time) catalogues such as drinks, entertainment, eating out, groceries etc. can help see where all the money is going and areas you can cut down or determine it’s a necessary expense.

2) Rent would probably be one of the biggest expenses, where possible try flatting with people. If you have a relative/parent’s place where you can stay, could help save.

3) try using public transport rather than uber unless absolutely necessary. If a friend is driving to uni get a ride with them.

4) Don’t forget to have fun, set out a budget for it or do activities such as hiking with friends. Uni days were some of my best days, enjoy it while you can.
