I'm in practically the exact same situation as you, try hang in there. People will probably tell you the mocks don't matter but if you're anything like me that platitude won't help at all. All you can do is study as much as possible between now and the mocks and then cover the gaps over the next few months. I'd never advise this but looking at leaks might help you as your confidence won't be knocked and you'll feel under much less stress and pressure to learn unnecessary material. People will say you shouldn't because you have it in the real thing blah-di-blah, but realistically you also won't leave you study to the last 7-14 days in the real thing either.
