Thank you very much for that advice. It has cleared things up for me. I think when she returns home in October we might look at getting this test booked in, and I will recommend she does the B1 version. Is there any recommended study material we could buy or is there no real way to study for it. Her English is very good, in reading, writing and speaking.

Also, is ILR and citizenship the same thing? She can apply for those once she has been living here for several years?
