DS-260 questions on attended education and previous addresses

[fiskefillet 1]

Hi, I have a few questions on this form in regard to past addresses and education I am soon going to submit.

This might be a stupid question but one I have not found asked here already. When filling in education I have attended,  should I put all education I have ATTENDED (what they ask), or actually COMPLETED? I lived in the UK for 6 months as I was enrolled and attended a university there, but did ultimatelly not complete the program and get the degree, as it was not for me. I have written this address on my past adresses, but should I also include my stay at the university under education? I suppose it is wrong to list the degree as something I have passed, when I havent, but it would help explain why I listed the address under past adresses..

Second question: how strictly do I have to know when I lived somewhere? Some stays of mine I do not remember if I moved in in july or june, so will have to guess, and give an estimate, will that be ok, or could I get into trouble?

EDIT: I realise that they ask what degree I recieve under the education question, so perhaps I should avoid filling in an education I did not pass.
