KPMG graduate scheme

I do not know anything about either of these schemes, however, I can say that sometimes we scare ourselves out of doing things that are actually good for us. It seems like the scheme you have been offered will be a challenge and you will have to relocate which can be scary, but think about what you might be able to get from this, meeting new people, learning new things etc. Focus on the possibilities that a challenge can bring rather than the uncomfortable aspects.
