Yes you can download it to a point.
What you have to do is to start off by "searching" for a group of questions, i.e. all of the MET ones, start it going and leave it, you can then open as many windows as you like to start off more questions on different subjects. You can then disconnect from the internet and still answer the questions but if you switch off your PC you will lose the info.
When I did Mod 2 with Bristol I opened a window with all the subjects questions on and transported my laptop to the exam venue leaving them open, I then went through them as and when I needed to.This is the only viable way of doing it that I know of.
