Popcorn? Nuts? might need a nutcracker at the same time.
And for anyone who is asking whether food is allowed, it is but there may be no labels at all and there is a high chance it will be checked for cheat sheets. Also many moderators don't know about this and will flat out disallow food. Though I like to have some boiled sweets just to suck on so I would take a copy of the rules to each exam if they tried to stop me from having them and point it out.
It's the same for if you finish early or you just think you've failed and can't be bothered to hang around. After 45mins (maybe an hour) you are allowed to leave the exam whether it is finished or not yet still some invigilators won't allow that and it is annoying when you finish early or you just realise you have completely failed and you have to sit there for 2 hours reminding yourself how ****ed you are.
