Hi Mary, I have to agree with others here and tell you to stop worrying it wont change anything, my Vanessa has completed her online application and has her appointment next thursday to hand in the application with documents.
From theses threads and answers to your questins I feel your application will be perfect. Perhaps i could suggest that if you feel you have included information that needs further clarification or explanation then this could form part of your supporting letter from your sponsor.
Good luck,
Relax be Happy.
