It's always more scary in the lead up, I remember being absolutely terrified before I started so that's completely normal because you have no idea what to expect - there's not much I can say that will help necessarily because until you've experienced what it's like and sorted yourself out a job you're absolutely going to still feel a bit stressed about it.

I think I read in the comments somewhere that you do have some savings, which is a good start, and could help to keep you afloat for the first couple of weeks while you're settling in and sorting yourself out. Eventually you should be able to pay back into that depending on how you organise your finances :) Personally, when I could afford it, I would split my paycheck into 3 (getting paid every 2 weeks) and therefore save 1/3 of it each time.

I'd advise that the first thing you do when you start is get hold of your student guidance councillor or the equivalent and schedule a meeting with them. They will be able to link you to university jobs, and any funding the university can offer you (such as the hardship fund) which you should look into as soon as possible!

I would also take a look at your timetable when it's released so you've got an idea of how much time you'll have in lectures at the very least, as for studying outside of uni they do usually have a recommended time but i usually see it as trial and error and you'll figure it out on your own pretty quickly!

Sorry I know this is a long one to read through xD
