Lots of excellent info on there.
Personal advice:
- I would use a mainstream OS that just works in case you have tech issues with proctoring if you don’t already run something in that category.
- Also, if you don’t decide to do the writeups for the 5 points ( I didn’t ), at least do a mock write-up of a few machines. Get the formatting the way you want so you can just cut and paste for your submission. Trust me, the last thing you are feeling after that exam is writing a report. Make it easy on yourself so you can focus on the important stuff, like not messing up the rest of the submission process…
