That is the only theory I have heard as to why teachers say that they are incompatible that makes sense to me.
Shouldn’t be. As long as you are on the same hardness scale it should be fine. The standard number 2 pencil just means its a medium-hardness graphite or HB on the grading scale. An argument can be made for the finer tip of the mechanical pencil can damage the scantron paper, but one should be able to fill in a circle without pressing so hard it damages the paper.
Aren’t mechanical pencils incompatible with scantrons?
Lol no, never, why?
