Ielts is not easy, its an all day long test, but the pass mark is about 4, sure some of the A1 equivalents like toeic are probably easier http://www.uk.toeic.eu/toeic/uk/abou...visa-purposes/
Ielts there are 2 versions, general (easier) and the academic (more difficult) version, my wife has taken the academic one a few times over the years
