A few schools like Dartmouth and JHU require you to type out your responses to the paper app. Have any of you used whiteout or some other corrective measure to correct your mistakes? Also, for JHU, if you screw up the paper app they send you, is it ok to just use a photocopy of the original and type it out again? I ask this because JHU prints their app with blue ink and a harder piece of paper. I'm wondering if this is ok.
