I have an exam next week, at my local FE college, and the tutor has told us not to use rub-out pens because the ink can disappear if it gets hot. Is that so? Do schools discourage their use in exams too, for the same reason? I know they use friction, but I'm less sure if heat, without friction, would have the same effect.
