I don't see why it would be. First or second year, you get the same amount of loan. And same goes for whatever subject your degree's in. I can't say for sure, though, as this has never happened to me.
Best thing is to ring the SLC and speak to a nice Scottish person. They open Sundays, do it tomorrow

I'm sure it'll all be okay. My dozy sister wrote on her loan application that she didn't want any loan! Then she got the payment schedule saying £0, panicked, rang them and they said "oh! Okay then!" and have sent her a new payment schedule promising her £3000/year! Lol
