Exam 1 Computer Marking

[Coloratura]

How 'sensitive' are the computers that mark the Exam 1 Answer sheet of Further Maths are?

I shaded the bubbles kind of hard so that when it rubs out, it can still be seen (faintly). Would the computer consider these as the 'selected answers'? Because I selected a different answer and anxious if the marking computer will consider this as two answers, thus marking the question as 0 marks. (However, from the human eye, the answer I choose (shaded) is distinct and visibly clear.)

I know, I worry too much.

It should be fine, double shaded answers are often human proofed!
