Also, I am doing some research into th IELTS test now, whether to go for A1 or B1 and it says that the results are only valid for 2 years...if this is the case then there is no point going for B1 right now is there as it will be out of date by the time we go for the ILR in the future?

Lastly, can someone point me to the right place to book this test? Where is the website?
