Student Finance

Hi, I'm a bit confused on what happens on A level results day with student finance once you get your University offers and can someone please try to clear it up for me.

So, I've already applied for student finance and everything has been accepted. I'm just wondering if I don't get accepted from my firm choice offer which I chose for on my student finance so I now have to choose my insurance choice university Do all the changes to student finance get automatically up dated or do I have to log and change it if I didn't get my firm choice offer? Also, what would happen if I were not to get accepted into either my first choice offer or insurance choice and had to choose another university through clearing, what would I have to change for student finance to still get paid on time?

Thanks

FYI all my evidence had been sent and checked and I am eligible to receive student finance
