Here are some test samples. Take note that Academic training is for someone who would be for professionals (i.e. nurse, doctors, etc.) and not for settlement visas. She can also just search more in Google coz there are plenty of samples. https://www.ielts.org/about-the-test...test-questions

Anyway, she can either take the Life Skills test or the General Training..it's really up to her. But B1 level for these 2 tests would be better. You can skim through the IELTS website for further details of these tests.

She would be able to apply for ILR after 5 years or living here (2.5 years of her entry settlement visa + 2.5 years of another visa extension called FLR). Then she would be qualified for citizenship after ILR (not sure though how many years required for that because they keep on changing the law!).
