Thanks and i do see it as constructive :) i did not mean this list as a set of questions which are the type you get, simply as a list to test your knowledge - if you can answer all the questions you know all the syllabus content, and if you can't answer some, you know which things you need to revise. thanks for the advice :)

Yeah I can do some for the three sciences first units, and for Germany 1918-45. Do you have any preference e.g. notes/cards and which areas of the specification in science? :)x
