I’ve used an erasable pen for my first 2 exams before an invigilator said today in my 3rd exam we weren’t allowed them, the invigilators in my first 2 saw me use it and erase stuff and said nothing (I get a smaller room for exams so sometimes it’s like 3 people in a room) but now I’m worried because I’ve searched it up and apparently it’s risky to use them?
