Hi! you can apply through the directgov site. All the details are on a thread somewhere, but i can't find the proper link, sorry!
They will have most of your details already on file, it really wont take you very long at all. I had been dreading it, incase i messed it all up, but it's alot more straight forward for your 2nd year!
From what i have read, there is quite a back-log, so the sooner you apply the better really. Sorry i couldn't give you the link! Maybe you could have a look in the 'applying for student finance' in this forum? It is around there!
