Considering that it doesn't have to be paid back until you are earning, would it not be worth accepting it just incase things aren't as easy another year, and if all else fails pay it back at the end, or cancel your final years loan instead? That way you are guaranteed to be secure financially through your studies?
Otherwise, I don't think I've ever known anyone cancel a loan 😂
Personally I'd would accept it and save it, depending on how long you've got of your degree, it could come in useful. Use it for a study abroad scheme, or a sandwich year?
I'm currently offered 6,000 for my first two years, and that only covers my accommodation 😭
