First time I did N5 there was no clock and I had no watch. It was the worst.
After that I bought a cheap watch which I don’t know where I put now , but after the first time, all locations I have gone have a clock in the wall.
If I have to add something for the listening, while you can take notes on the exam sheet and then transfer to the answer sheet, don’t do that in the listening.
As soon as the recording says the number of the next problem, you should have already filled down the answer. You won’t have time after that.
Also don’t open the exam sheets until they tell you. And once they tell you, do a quick glance at all the pages to see if you have all the pages properly printed. Raise hand if there’s a problem with the print out.
They explain this, but I’ve seen people (maybe because they are nervous af) make the mistake.
