I don't think it was THAT difficult, but you've only got (I think) 12 minutes, so read the question (10 seconds?), find the relevant tab, which is not always clear (maybe 20 seconds), read through the various chapters in order to find what you're looking for (another 20 seconds at least?)... so I was around one minute per question...
Don't know... we'll see...
Good luck to anyone else
