You will definitely need your laptop and a mouse for one of the tests if not two.
You can open it up though and answer most of the assessment exercises on your tablet then login via your laptop for the spatial/motion exercise.
Good luck and pay attention to the time remaining. I had a dog be sick at my feet during a 2 or 3 minute 5 question exercise and only manage 2 or 3 questions before it timed out. So I've probably ruled myself out of the Dublin based assessments now.
