If any of the items are NOT satisfied when your Scantron is handed in and/or when your Scantron is processed one point will be subtracted from your test total. My Scantron: uni25A1 is bubbled with firm marks so that the form can be machine read; uni25A1 is not damaged and has no stray marks (the form can be machine read); uni25A1 has 15 bubbled in answers; uni25A1 has MthSc 101 and my Section number written at the top; uni25A1 has my Instructor’s name written at the top; uni25A1 has Test No. 3 written at the top; uni25A1 has Test Version A both written at the top and bubbled in below my CUID; uni25A1 and shows my correct CUID both written and bubbled in.
