I am just confused that in real exam do we get questions/task in hardcopy or they apear on the screen and you can take notes from there if wanted? like topologies and etc....
Everything you will get in terms of Tasks and Diagrams will be on screen. Though you will have couple of A4 sheets and coloured pencils using which you can redraw diagrams and all on paper for your own sake.
Following should give you good idea :
Try to write your solutions for each task on notepad. This may help you review your answers efficiently.
As pointed out, everything will be on screen and you will have paper to work with yourself.
You need to practice putting everything into the screen because the screen is big enough. This will help to have a quick view and avoid clicking back and forth.
Notepad is a good tool to put the summary of your work for review as pointed out. But these need practice before real exam.
